I find it hard to hate things. I tend to be optimistic about a lot of things, taking the best from a bad situation or person. However, if someone or something does something I completely disagree with (i.e. cheating with my coursemate who wasn't aware the guy in question had a girlfriend, causing her to feel terrible.) then I will dislike them. If they do more things that pisses me off (using my stuff without asking and expecting me to clean it) then I may eventually hate them.
This was over the course of a whole year by my flatmate by the way. He cheated on his girlfriend, who genuinely seemed to love him, roughly once a week. My whole flat hated him, especially as he kept trying to one up all the other guys in the flat (including me)
CAPTCHA: Be my friend? (with a heart above the "i" in friend.) LOLOLOLOL, given my last thread about friendzoning, this is hilarious.
