Oh wow. I offer to hold people's kids all the time. Rouge will attest to me going somewhere and ending up carrying someone else's kid for hours.

I do it even if they're not upset. The parents are having dinner and baby is making goo-goo eyes at me? I say 'Naw, he/she is gorgoues! is he/she good with people he/she doesn't know? Does he/she go to anyone?'

Funny thing is, most times people are pretty happy to hand baby over to me. Even you PZ :P . Or maybe I'm so thick skinned I don't even notice if someone didn't want me to pick up their child. o_O

That's completely possible too.
