If you were a parent, what age would you allow your child to have a serious relationship?

15. They’ll most likely be mature enough to make good decisions by then.

DO IT AT 0

Whenever they feel ready...

16, maybe fifteen, but DEFINITELY no younger.

Probably 13-14... I mean, that's how old I'd like to be. /I'm 12 though, so I'd understand if they really liked someone at 12, IF they were mature enough..

15/16. Somewhere in there.
They will be old enough to make good choices (unless they don't think, like many people), but not too old where it's a bit cruel of the parent.

17, maybe 18.
