Pests come in many shapes and sizes. We've mentioned many in the preceding pages, such as cockroaches, flies, spiders, mice and rats. But there are also those annoying biped pests, your fellow students. You know, the guy who always pops in uninvited and proceeds to eat all of your food, and the girl with that high-pitched, annoying laugh. And what about that kid who's always whining to you about her love life? Keep your room nice and quiet, and your nose buried in your books. Maybe have some classical music softly playing in the background. That should drive them away every time.
