Video games, DVD's, and junk food.
I'm so grateful that I have a job. Because money is pretty tight in our house, my parents have really cut back on shopping the past year or so, leaving me out to dry for having decent food in the house to eat (by decent, I mean junk food, obviously). Now, though, that's not a problem.
Also, I like being able to buy video games whenever I want, provided it's on a week I get paid. Growing up, I usually only got new games and stuff at or around Christmas or my birthday (with rare results in between for good grades in school or whatever).
