I have been rude when someone announces that they are pregnant and I ask them what they plan to do about it.


I think it is really rude when someone asks how much money I make. That's a private matter to me. I have found the best answer is "why do you ask?" That usually gives them a hint that they are getting a little too personal.
Another kicker is when people ask me why I got a divorce. Relationships can be so complicated that answer would take all day to give it justice.. I think it is off limits.
