I’m not the best at the dating game I concede but I usually use the first date to find out about what kind of music, movies, entertainment, etc we like, some small bits about family: siblings, parents, nieces/nephews, places we’ve traveled to, etc. I don’t know. I don’t think it’s right to ask someone you just met about their relationship with their parents. That’s something I understand you do as the relationship gets more intimate. That he singled out father was telling to me.
