Being a computer science major means I get asked to fix people's computers. A lot.
Ocassionally, I'll oblige them and offer my services to fix the problem. And more often than not, there's just as much that they're doing wrong as their computers are. People tend to forget that machines need to be taken care of. Just because they can't feel, talk, or even nap in your lap, doesn't mean that they never need some TLC. Computers especially, are extremely vulnerable machines. Like a family pet, a computer needs to be looked after, because it certainly doesn't have the capacity to look after itself.
