A friend and I were talking the other day about meeting new people, and how important it is (or isn't) to have things in common. He was a little concerned that a woman he met only has one real hobby - and it isn't one that he shares.
I said I didn't see that as an issue. It's not like they need to be tied together at the hip all the time. So, she goes off and does her thing, and he'll do his. If she only has one thing she's really into - she'll probably be open to just about anything when they are spending time together.
He thought about that, and agreed. It's not as if he wants to meet someone with whom he shares everything. Everyone needs time to themselves. If you share every hobby or interest - you'll get sick of each other pretty quickly.
On OK Cupid, one of the profile questions asks how much you want to have in common with a significant other; Everything, More than half, Half, Less than half. My answer is Less than half; but I've seen plenty of people who want to have More than half, or even Everything, in common with their "other."
That seems...boring to me. Half the fun of meeting someone new is learning and experiencing something new. If we already share everything, I won't learn anything - and I can't teach anything, either.
Guess I'm just a less than half kind of gal.
