Like a PP, when people ask me questions and then don't wait for the answer.
When people ask me for advice and then tell me I'm not qualified to help them when they don't like my advice. ie In college I knew a girl with a boyfriend who couldn't be bothered to spend time with her and when he did he was verbally abusive. She asked me what I should do and I said simply "Well if you don't like how he doesn't spend time with you, and when he does he isn't nice to you, break up with him."
"But-but I don't want to be the bad guy!"
"You'd rather be treated poorly or ignored?
"Oh what do you know about re
lationships? You've only had one boyfriend your whole life!"

I chose not to point out that the one rel
ationship I had was already about 2 years in length by that time and she'd had 3 miserable re
lationships in that time because she refused to be the bad guy.
