As with dialogue, you have to observe real people to be able to replicate that realness with words. So grab a pen or pencil and something to write on and get out into public. Observe strangers in a public place, like the mall or a coffee shop or even the library. Write down descriptions of them. What are they wearing? What color is their hair? How are they walking? Are they striding confidently, or are they hunched over and furtive? What quirks do you observe? Do they tap their fingers as they drink coffee, are they chewing on a pen? Are they laughing to themselves? You don't have to write an entire description while you're observing, just jot down a few notes to give yourself ideas for later. All these observations tell us something about a person and you'll need them for when you start describing people. Pay attention to your family and friends. They all have habits and personality quirks that you've become accustomed to. Start jotting those down, as well. Describing people you know well can be great practice. You aren't looking to copy them exactly but to figure out what works for them and why it works. Analyzing someone else's work is important, because it gives you ideas on how to make your own work do something similar. "Crowley had dark hair, and good cheekbones, and he was wearing snakeskin shoes, or at least presumably he was wearing shoes, and he could do really weird things with his tongue. And, whenever he forgot himself, he had a tendency to hiss. He also didn't blink much." This description gives an outline of physical features, but leaves most of the formation up to the reader. What it does do is highlight Crowley's "otherness," because Crowley, is in fact, a demon. Other things that can be gleaned from this one passage: Crowley wears good clothing (the snakeskin shoes), he is trying to fit into being a human, but not quite succeeding, and he doesn't always maintain control over himself. "Suddenly Frodo noticed that a strange-looking weather-beaten man, sitting in the shadows near the wall, was also listening intently to the hobbit-talk. He had a tall tankard in front of him, and was smoking a long-stemmed pipe curiously carved. His legs were stretched out before him, showing high boots of supple leather that fitted him well, but had seen much wear and were now caked with mud. A travel-stained cloak of heavy dark-green cloth was drawn close about him, and in spite of the heat of the room he wore a hood that overshadowed his face; but the gleam of his eyes could be seen as he watched the hobbits." Aragorn's introduction gives clues that he is not what the Breefolk think him--his clothing is well-made, but it is worn. He smokes a "curiously carved pipe" which speaks to his odd origins. Tolkien shows him being interested in the hobbits, but being removed, casting onto doubt his intentions. Notice that both these descriptions are part of the story. They set-up further action instead of stopping it to describe every detail. The Tolkien example, frames the first look at Aragorn as being done by Frodo, who is noticing the character's interest in him. This passage also highlights Frodo's own heightened wariness.

The exact appearance and location of the test button will vary from unit to unit. However, on most models the test button is located next to an LED light that periodically flashes. If the circuitry in your detector is working, the alarm should sound for 3 to 5 seconds before automatically turning off. This alarm will be pretty loud, so you might want to cover or plug your ears. Pushing the test button does not test the actual CO sensor; it tests to make sure the battery and circuitry in the unit is working correctly. The alarm should sound immediately after you press the test button. If it doesn't, try again. If you still don't hear anything, you may need to change the batteries in your detector, although not all CO alarms have replaceable batteries. Some CO alarms now have a sealed 10-year battery and an automatic timer to tell you when the alarm needs to be replaced. It will start to beep or chirp a code periodically, telling you it needs replacement. Look at your unit's instruction manual to identify what the code means. To make sure the replaceable batteries stay fresh in your CO detector, change them every 6 months, but no less than annually. If you live in a place that recognizes Daylight Savings Time, switch out the batteries whenever you change your clocks. If you change the batteries and the unit still doesn't work, or it continues to give a low-battery alarm, it may have expired. Replace your CO detector. Having a set day of the month for testing your CO and smoke detectors will help you remember to do it. For instance, you might always check on the first day of a new month. If the CO alarm starts to chirp or beep periodically, check to see if the battery needs replacement by pressing the test/reset button. If the unit continues to beep or chirp after the test, and it does not have a replaceable battery, the unit may need to be replaced, having expired. Check your user manual for specific instructions on how to turn it off and to properly dispose of it. Install a suitable replacement immediately.

Calla Lilies will survive outdoors over winter in mild climates that don't experience much sustained snow, deep freezes and heavy prolonged rainfall in the colder months. They can generally cope outdoors through winter in zones 8 through 10. This means that they can survive in temperatures that do not drop below 30 to 35 degrees F (-1.1 to 1.7 degrees C). After flowering has ended, refrain from watering and allow the plant to die back. Try to refrain from cutting the foliage until it has withered away. If you are overwintering outdoors, apply a mulch of about four inches of straw or evergreen branches. You can also put them under an upturned pot or cloche. Do this in the fall before the ground gets cold.
