Was at a BBQ for my friends birthday at the weekend. I was talking to a friend of hers who I'd not met before. Her uncle came over and joined in. Was asking if I was married, I said yes. Asked if I had children. I said no. (We're currently ttc so I don't like this question anyway but that's likely as it's a sensitive topic currently) then he asked if we were practicing conceiving?! I just sort of stared at him until he changed the subject (to the other lady: 'well you must have kids already' - she didn't.)
He seemed a nice guy other than that but aibu to think it's weird to ask a stranger (who is young enough to be your daughter) about her sex life?!
