Sister/Sis… Mister?

“Tell me is there any more room for me in those dominant genes?!”

You are dating someone and she tells you that she has siblings. Okay. Eventually she shows you pictures of them. Cool. One day you finally meet them and you get along great with them. Whew. Meet-and-greet nearly accomplished, everything is dandy until your date turns a certain way and now you notice something. She looks just like her brother. A resemblance -no matter how much you try to deny it- you see more than ever before.

Oh no. There is no ‘reset’ button either. You can’t remove the dots once the connection is made. They’re almost twins now! Oh, yeah, others might say they don’t really see it, good for them. But they aren’t you; you can’t ignore it. And it will probably become most poignant at the worst possible times too. In fact, the only thing that can top the ‘sister-mister’ is a father-daughter resemblance.

So what do you do? Also, is this an issue? What about when the genders are reversed?
