Some background: 
Just started dating this girl and I'm not sure if she's White or Mexican (her last name looked hispanic to me but i haven't bothered to ask her) but I'm Black and Mexican. So we were texting each other an hour ago about how cold it's going to be tomorrow, work and our well our 2nd date went. Out of nowhere she asked me my ethnicity and I was shocked. I answered her question first, then said that her question was a little out of left field. I used to get asked a lot growing up and had no problem answering but nowadays it's really rare that anyone asks so I never worry about it or prepare for it. She said she was sorry but I let her know that it was okay because she was curious and I was glad she was. AITA?
