Dating a girl with the same name as your sister
We've known each other 30 years, and I'll bet that's the total times we've addressed each other by our given names.
I did for years, and not only did he have the same name as my Dad but he looked like him and in many ways acted like him too. I tease him that he's off the hook if he accidentally calls out the wrong name, but he assures me that he has us straight.
And, after only two or three days, I've gotten a lot more used to calling my guy by his name and not thinking of Dad. I was dating a woman who had the same name as one of my sisters - pretty common name, no problem at all - and the two personalities were completely opposite, proving that the name itself was no signifier.
I may get almost completely comfortable with it, but I doubt I'll ever be screaming out his name in the bedroom. Still, the relationship with that GF wasn't going anywhere, so...
Oh, there is one incredible benefit of him having the same name as my dad. For the last three years I've been dating a woman with the same name as my brother's ex-wife (no, not his ex-wife).
It means Dad can't call him by the wrong name and make it look believable. Now the odds are pretty slim that I would date someone, well besides the fact that I'm a big loser at love, named Cinderella. Again, no problem, just some amusement among the family. I have noted in my own mind that if I ever do meet a woman with the same name as my mother - used to be more common, but has gone out of style - I will have to check in for therapy.
Of course, as she is far too polite to ever admit such a thing, I’ll likely never know.
I dated a girl who had the same first name as my mother. Cliffy and I have been dating/married, I've probably called her Kathy less than a hundred times. Athena is named after his father which is coincidentally my father's name, too). My mom's name is Mary but is alternately known as Mary, Marie, and Maria and there is no way I am going to cut myself off from all the women with those names, especially considering I'm a bit fond of the nationalities that usually employ them. As for sisters, the first girl I ever kissed shares my youngest sister's name and it never even dawned on me until this very moment.
My father and brother have the same name, which is one of the most common male names in the US (I usually see it on lists as #2).
