Would you leave your 15 year old with an 18 year old friend whilst you go away for a few days?

Nope, our 15 yo is an untrustworthy airhead

No

From the standpoint of safety, maturity, and fending for herself, I would. I would actually leave her completely alone a couple of days with clear instructions, and there is no problem with this where I live. Six months ago I would not have, she was not mature enough.
I do think, though, she'd just have her boyfriend stay here, so we won't be doing that (the boyfriend is great, I just don't think a 15 year old couple should be spending all that time alone together).
