I seriously agree with the food wasting thing. In high school I saw students spend $2.50 on a hot lunch, eat only the main thing and throw everything else out without a care. It got so irritating to see, I started going up to people about to dump their food and asking them for it.
The only food I ever threw out at school was the apples. I like apples, but those tasted terrible, and I swear they dehydrated my mouth somehow. I didn't want to throw them out, but I could never finish them and had no choice.
