I'm 26 and I had a job interview today. I live in my own house but I've come to my mum's house for dinner tonight. I took the day off work for the interview and told her about the interview when I arrived at her house. She's said she's very hurt that I didn't tell her beforehand and got visibly upset. She said no matter what I say, it will hurt. AIBU to have not told her before the interview?
