Bad / Unfriendly
irritate - To make someone angry, or annoyed; or to make apart of your body sore or painful.

After the mother spent hours peparing the Friday night meal, she was irritated when the whole family ate quickly and left without thanking her or even saying anything in appreciation.
intolerant - Refusing to allow others to do or believe things that you don't agree with.

When people try to dialog with others, and both are intolerant of each others' points of view, it often just degenerates into a shouting match, with neither side listening.
