A friend recently told me it's perfectly acceptable and the 'done thing' for teens who are celebrating their 18th birthday out with friends, for the friends to pay for themselves.
That doesn't sound right to me. I think once they are 19 and organising their own birthdays (I hope!) then that's when they go out for drinks or whatever and buy their own drinks.
Bit of context - DS turning 18. I'm on a tight budget. DS quite shy and not too sociable, doesn't want a huge fuss or party, not interested in alcohol, not too excited about meal out with friends. He loves gaming and there is an experience that I think he would love so I'm thinking to pay for him and a couple of friends. Then maybe they could go and get a quick bite and pay independently for that?
In contrast, friend's DS went out bowling and for a meal - all paid for themselves! The done thing in their school apparently. Not sure if it makes a difference but her DS goes to a private school and DS goes to school in a poor area. If DS' friends had to pay for themselves, I'm not sure they'd even go.
