My favorite snack is whatever sweet thing is in my house. Everyday when I get home, I have icecream. It's unhealthy, but at least I'm not addicted to it. I don't care if it's out of the house or not. I also like cupcakes and tapioca pudding for a "get home from school" snack. Cookies are lovely as well. There's one thing, though, that I enjoy more than any other small snack ever. I don't remember the exact name of them, but they're Italian wafer cookies things. It's chocolate scrunched in between two wafers. :3
Healthy foods are nice snacks too. An apple with peanut butter is a great snack when I have enough initiative to slice and skin the apples.
