People persistently calling you by the wrong name.
People who are always late.
People who let others do all the work but who like to share the glory.
People who constantly check their phone when you are talking to them, particularly in a social setting like a catch up meal. I stopped seeing a friend because of this.
People who make assumptions on who or what you are without any foundations. A colleague in her 40s who had given up having a child due to fertility issues, suddenly got pregnant. I said congratulations when I found out. She said she worried about mentioning it to me, she knew I was desperate for a child. I have never been desperate for a child, I had no urge to have kids at all and had never expressed a desire to have them to her or any colleague. She was projecting her desires onto me. She looked unconvinced when I said she had got me wrong.
People who only let you get a couple of words out before they speak again, they want all the airtime. Or speak over you loudly.
