I think I'm going to say someone was a bitch for acting like a bitch
Why would you call someone that?
Because I think they're rude, disrespectful and unlikeable.
I understand that you may have issues with this person's behaviour, but it isn't okay for you to call them crude names. Find some compassion for this person and love them no matter what.
You are too sensitive. I just want to vent.
I understand, but you can vent without using derogatory language to describe this person. I really think you should try to release your frustration in some other way, that doesn't involved being rude to them.
