15th birthday, going for a meal with my friends helppp?

Choose a different restaurant to be considerate of other people that may not be able to afford the prices of the 'nicest restaurant' at the age of 15. That can be a lot to ask since 15 year olds don't usually make their own money. And then to get a taxi?? That's even more money you're asking them to pay. Pick a different place at a different time so that the people you want to come, are able to make it there, and afford it. Your birthday is about fun w/ friends and family, not about impressing friends and family. Have fun!
