Especially people that pride themselves on saying it as it is and being honest with what they say?
An acquaintance that I see on regular nights out with a group of friends regularly offers unasked for advice, and is quite abrupt and direct with how she says things. I am talking about statements like "You're oversensitive", "You're being paranoid", that kind of thing. She always says how she calls a spade a spade, and how she is honest, as people like and admire honesty.
I have now apparently upset her as when we went out last weekend she asked for advice regarding her son's school reading (she thinks he is super-advanced). I said that I was sure the teachers at school would give him reading books appropriate to his level (he is year 1). Apparently I dismissed her and was abrupt (!!).
I have also come across people in the past who always make sarcastic jokes and comments but hate having the same done to them, and people that ignore texts but hate it if you don't reply to them instantly!
