I never realized just how wasteful and ungrateful people were until I attended university. People would take one sip from a pop and chuck the rest, have a whole chicken but only eat the legs (my roommates would give me the rest in return for doing their assignments after finding out I liked chicken), and go to the cafeteria after claiming how terrible their food was, heap food on their plate, take a bite or two and throw the rest away. People always asked if I was a starving African kid because I'd eat every last bit on my plate (even gravy or sauce). They were the same way with clothes and everything else.
