Something feels wrong about shipping like 7 year olds that doesn't with the 10 year olds. Probably because the 10 year olds don't really seem to act their age and instead act a bit older, whereas the 7 year olds do act their age.

If (not when) they're ever older, I could see this working out, but as it stands now, they're literally 7 (it feels so weird not using 10 as the number in that phrase).

Also they've never met.

2/10 at current situation.
