Dating someone with the same name as your sister
I dated a guy in college with that name, it didn't seem like a very big deal.As other posters have said, in my mind my dad's name is "Dad" anyway.
Later on, my parents got divorced and my mother remarried a man with the same name as me. So, I'm not very likely to date someone who goes by the same name as my mom, and if I met someone with that nickname it would definitely be an issue (not "I'm not going to date her", but "that's kind of wierd").I was in a class that, for some reason, had about 4 or 5 students in it who had either the same given name as my mom or a slight variation. But on the other hand, Edward isn't a terribly common name for men in their mid-twenties to mid-thirties, so I don't think it'd be much of an issue for me. I think if we took a poll, a lot of people would have Mom issues such as that. Perhaps you're thinking of a different odd thing, though.
