I think I might have just been quite rude, so do tell me if you think I was and I will apologise to her.
She was asking me questions - are you married, do you have kids and so on, and I was responding in the negative. She then kept saying 'awwwww' sympathetically, with a head tilt. I said in the end politely but a bit tersely 'please don't do that!'
Was I? I feel bad now!
