It's the kids that seem to appreciate it more than the parents, funnily enough.

I agree with the replies to this saying that the fact it could lead to drama should not prevent people doing things like this, but I can see this causing trouble/resentment too.

I think a lot of the other unasked for examples given could also cause resentment. Perhaps often the right thing to do is just taking the risk.

Things have always been able to go wrong. That's not a reason to stop doing things. Oh no, you might get an ear full from an angry parent once in a while. boo hoo.
