INPUT ARTICLE: Article: Remove the hair catcher or filter from an affected shower drain and clean it out thoroughly, removing all the hair tangled inside it. The key in destroying the drain fly's breeding ground is removing all hair, grime, and debris that the flies might lay their eggs in. Pour 1 to 2 gallons (4 to 8 liters) of warm water into the drain to moisten it slightly. Note that this is only needed if the drain is not used on a regular basis. Drains used on a daily basis are moist enough without taking additional measurements. Work a metal pipe brush into the drain, extending it as far down into the drain as possible. Twist the brush while slowly moving it up and down to remove grime from the sides of the pipe. Insert a plumbing snake into the drain and twist it through the pipes to pull out clumps of grime that lie further down. Apply roughly 4 oz (125 ml) of the cleaner around the edge of the drain. Applying the cleaner to the edge of the drain allows it to coat the sides of the drain and pipe as it glides down. Gel cleaners are formulated to remove organic matter. You could also use enzyme or bacterial drain cleaners to remove organic material. Vinegar, boiling water, and bleach are traditional remedies for getting rid of drain flies, but many experts insist that these methods are not effective. Baking soda and vinegar poured down the drain may kill the flies; it will clean the drain at least. You may need to repeat the same dosage of drain cleaner once a day for five to seven days total. After the drain cleaner has sat in the sink for several hours, flush it through with plenty of water. Use a plunger to remove any remaining organic matter trapped in the sink.

SUMMARY: Clean the hair catcher, if applicable. Moisten the drain, if necessary. Use a metal pipe brush. Fish out other grime with a plumbing snake. Pour a gel drain cleaner into the drain. Finish up with a plunger.

INPUT ARTICLE: Article: Don't get too obsessive, but taking a glance at their social media pages can tell you a lot about who they're talking to and where they're going. You might be able to see who they've become friends with recently or if they're liking a lot of posts from a particular person. To avoid torturing yourself, try putting a limit on how often you'll look at their social media, like once a day instead of once every hour. While rumors aren't always true or good sources of information, sometimes they are. Take each rumor with a grain of salt, but if the source is a trustworthy person, it might be worthwhile to listen. For example, if you hear from three different people that your crush was holding hands with someone at the movies, that's a clear sign that they are into someone else. Your friends may be able to see your situation with your crush more clearly than you can. Ask them for their opinions and to keep their eyes open when they're around your crush so they can clue you in to what's going on. You might get news you don't want from one of your friends. If this happens, don't get mad at your friend. It's okay to be upset, but remember that your friend didn't do anything to you. This works best if you know your crush's friends and can have a conversation with them without it seeming too weird. Keep in mind that this person may tell your crush that you were asking about them, but it could also give you some important insider information. For example, try saying something like this to your crush's friend: "Hey Ryan, I noticed that Jade has been spending a lot of time with Ben. Is there something going on there?" directly if they like someone. This can be a little risky, but if you feel that your crush has their eyes on someone else, it might be worth it to find out for sure so you can move on with your own life. Try to phrase the question in a non-confrontational way and make it seem like you're just generally curious about it. For example, you could say something like, "Hey Max, I was wondering if you were interested in Kylie. I noticed you guys have been spending a lot of time together." If they ask why you want to know, say, "Oh, I was just curious."

SUMMARY: Check out their social media to see what they're up to. Listen to rumors you hear about your crush and their love life. Get input from your friends about the situation. Talk to your crush's friend discreetly to see if they know any information. Ask your crush

INPUT ARTICLE: Article: A singly even square has a number of boxes per side that's divisible by 2. A doubly even square has a number of boxes per side divisible by double that 4. The smallest doubly-even box that can be made is a 4x4 square. Use the same method as you would with odd-numbered or singly-even magic squares: the magic constant = [n * (n^2 + 1)] / 2, where n = the number of boxes per side. So, in the example of a 4x4 square: sum = [4 * (4^2 + 1)] / 2 sum = [4 * (16 + 1)] / 2 sum = (4 * 17) / 2 sum = 68 / 2 The magic constant for a 4x4 square is 68/2, or 34. All rows, columns, and diagonals must add up to this number. In each corner of the magic square, mark a mini-square with sides a length of n/4, where n = the length of a side of the whole magic square. Label them Highlights A, B, C, and D in a counter-clockwise manner. In a 4x4 square, you would simply mark the four corner boxes. In an 8x8 square, each Highlight would be a 2x2 area in the corners. In a 12x12 square, each Highlight would be a 3x3 area in the corners, and so on. Mark all the boxes in the center of the magic square in a square area of length n/2, where n = the length of a side of the whole magic square. The Central Highlight should not overlap with Highlights A-D at all, but touch each of them at the corners. In a 4x4 square, the Central Highlight would be a 2x2 area in the center. In an 8x8 square, the Central Highlight would be a 4x4 area in the center, and so on. Begin filling in the numbers of your magic square from left to right, but only write in the number if the box falls into a Highlight. So, in a 4x4 box, you would fill in the following boxes: 1 in the top-left box and 4 in the top-right box 6 and 7 in the center boxes in Row 2 10 and 11 in the center boxes in Row 3 13 in the bottom-left box and 16 in the bottom-right box. The is essentially the inverse of the previous step. Begin again with the top left box, but this time, skip all boxes that fall in Highlighted area, and fill in non-higlighted boxes by counting backwards. Begin with the largest number in your number range. So, in a 4x4 magic square, you would fill in the following: 15 and 14 in the center boxes in Row 1 12 in the left-most box and 9 in the right-most box in Row 2 8 in the left-most box and 5 in the right-most box in Row 3 3 and 2 in the center boxes in Row 4 At this point, all your columns, rows, and diagonals should up to your magic constant you calculated.

SUMMARY:
Understand what a doubly even square is. Calculate the magic constant. Create Highlights A-D. Create the Central Highlight. Fill in the magic square, but only in Highlighted areas. Fill in the rest of the magic square by counting backwards.
