have you ever had any friends that are just plain stupid or react really strangely?

i have one. my friend got mad at me for telling her that at work, you can't really "be yourself" around your boss. i told her it's hard work and determination and that if you slack off all the time your boss WILL fire you. she then gets all teary-eyed at me and says "well james think about peoples feelings next time you go to say something like that." then also any time we argue, she'll bring up my sister's abrupt death to leukemia. every. single. time. what the hell?
