Yay. It's kind of funny because when I learned this stuff in school I was like "why do we have to learn about this crap that we already know? T_T" but I payed attention anyway because I was a nerd and had nothing better to do. And now I realize that a lot of native English speakers probably don't know which one is correct (or if they do, they don't know why) and it's probably because they didn't pay attention. So I'm doing slightly better than they are. ^_^
