Even if you and your sister have arguments, she's still going to be your sister. Figure out the best way to cool off and then come back to her. Apologize and ask her if you can move forward. "I'm sorry I got so upset about you being late. There was no reason for me to yell. Can you forgive me?" "I really thought it was a bad idea for you to date that guy. Sorry. I was wrong -- he is a pretty cool guy, and it's certainly not my place to judge and then tell you what I think you should do." "You were right. I was dressed completely wrong for that party and I had a terrible time. And since we had argued, I felt even worse. I should have come with you and your friends." You and your sister are together for life, and if your sister asks your advice, be honest while also being diplomatic and sympathetic. Even if it's not what she wants to hear, you are in a better position than almost anyone to tell her what you actually think and make her listen. She is also in that same position for you. Parental advice can sometimes feel meddling, but a sibling's advice is often just what you need. Your family is often your best support throughout your life, and your sister could be the most important part of that. She will be with you through the big events in your life, and having someone to turn to in difficult times that really knows you can be incredibly helpful. She probably knows you better than anyone else, and it's to your advantage to keep your relationship strong and close. Everyone has difficult moments, and sometimes a sibling can help comfort you better than anyone, and vice versa. It's usually not about giving advice -- if she wants it, she will ask -- but just about being there when things don't go well. Be a good listener. Really paying attention to her problems can be helpful to her and deepen the relationship the two of you have. If you don't like telling her how much you love her, do kind things for her. Give thoughtful gifts, celebrate with her when things are going well, and be there to cheer her up when life isn't so easy.

One-sentence summary -- Work through disagreements. Be honest with her. Keep her informed about your life. Be an emotional support. Make sure she knows how much she means to you.

Because single-variable inequalities only occur on one axis, you don't have to use Cartesian coordinates. Instead, draw a simple number line. These are pretty simple, because they only have one coordinate. You will be given an inequality such as x<1 to graph. To do this, first find '1' on your number line. If you are given a "greater than" symbol, which is either > or <, then draw an open circle around the number. If you are given a "greater than or equal to" symbol, either > or <, then fill in the circle around your point. Using the point you just made, follow the inequality symbol to draw a line representing the inequality. If it is 'greater than' the point, then the line will go to the right. If it is 'less than' the point, then the line will be drawn to the left. Add an arrow to the end to show that the line continues and is not a segment. Substitute in any number to equal 'x' and mark it on your number line. If this number lies on the line you have drawn, your graph is accurate.

One-sentence summary -- Draw a number line. Graph your inequality. Draw your line. Check your answer.

Your skin should react within 15-20 minutes of your doctor administering a skin prick or allergy injection test. Your doctor will have you wait in their office so they can review the results of the test. Allergy skin tests are more accurate when they are left on for at least 15 minutes and no longer than 40 minutes. If you received a patch test, it may take at least 48 hours for any allergic reactions to appear. You may need to return to your doctor's office to get the results of the test. Wheals will appear as raised bumps that are swollen or red, much like mosquito bites. They may itch or feel irritated. If you have wheals on any areas where an allergen was placed on your skin, you likely had an allergic reaction to the substance. If you are allergic to multiple substances, you may have multiple wheals. Wheals that are smaller than 3 millimetres (0.12in) in diameter may not be a sign of an allergic reaction. Flares are patches of redness that appear due to an allergic reaction. You may notice flares in the areas where the allergy skin test was administered. If you have flares and wheals in the same area, this usually means you are allergic to the substance. The presence of flares and no wheals may mean your skin is irritated by the substance, but you are not allergic to it.
++++++++++
One-sentence summary -- Check for wheals and flares 15-20 minutes after you get the allergy skin test. Look for wheals that are 3 millimetres (0.12in) in diameter or bigger. Check for flares that are bright red.
