I fully anticipate having to argue with my as-yet-unfound future husband over which fandom we're giving our children names from.
Also, when you go to a party, and the pick-up lines go more like "what's your alignment?" than "what's your sign?"
Good thing that I have a boy name (picked from dr.who, and SO has a girl name from a sci-fi book, and neither of us object to the other one. But that would be for fictional, as yet to determine if we want one, with each-other, kids.)
While telling my SO yesterday that I'm always in need/want of a kiss I told him it was a constant, like f(x)=yes.
I'm not even sure if what I said made sense and is a constant (tho I think it is?), but it made him grin ear to ear, he's the math wizz
