What are some traits of other adults that annoy the crap out of you? For me, it is laziness, time wasters, and braggarts.
People who have to be right often with little evidence. All are guilty but some are able to admit when they are wrong but others, never.
One-sided conversationalists, people who talk over other people or don't acknowledge what they say.
I think that's something many people have to learn especially us introverts. I have been guilty and sometimes need a reminder but am getting a lot better.
@JackPedigo Sometimes I run into that with people who talk a lot. You'd never know it from corresponding with me, but I'm actually pretty quiet.
