It isn't age. Dealing with minors opens a whole can of worms. I would have made sure the parents were involved as well.
And while I would have to say the other person was being somewhat rude, I would have refused to hand the animals over as well. Parental persmission issues, but you were also talking about cutting corners on care, and giving the animals away. A phone call goes a long way to avoid misunderstandings. I'd try that instead of MSN next time.
I am highly prized for my meat. :eb:
