Mutiquote button, use it, please. .
Also, you make it sound like your girl HAS to share a common interest in ALL your interests. I suggest breaking it down o perhaps looking for someone who shares an interest with one, maybe two of yours, not every interest.
If I based finding a girl on common interests I think I'd be shit out of luck, how many girls do you know who have an interest in toy and model cars and lego, and building bicycles?
First off... LEGO FOR THE WIN!!!!
*Noob just found multiquote button and face palms*
NO she doesn't HAVE to share ALL of them but it would be very cool, more of will accept them but not really care too much at least.
