They thought he was my dad and moms husband

I needed furniture for my room (just moved into a new apartment) so I went to ikea with my mom and boyfriend. My boyfriend is 34 super tall (6’4) bearded and with a sprinkle of grey (looks his age doesn’t look too old) I’m 23 (4’9) small and skinny and look 14. While we were walking around looking at dressers some lady started talking to my mom and somehow got into the conversation and said something about me n my boyfriend and thought we were father and daughter. Meanwhile me and him were laughing and having a good time being handsy (not in a gross way lmao very much public friendly (I’m not a huge fan of pda mostly bc of the looks we would get) I wanted to cry so embarrassing.
