I read somewhere that Sirius is the guy you want to have a fling with (dead sexy and has that motorcycle-riding bad boy edge) but Remus is the guy you want to marry (level-headed, good with kids, and always has chocolate on hand when you get PMSy and need it).

Don't worry, we'd share the last piece of chocolate cake. A forkful for me, a forkful for him, I'd get a bit of frosting on his lip and have to lick it off...
