I'm 18 and my Dad won't let me and my friend go to London for a day Watch
What can I do?
Does he have a reason not to trust you to go? Really as long as you’re living with them you should respect them enough to listen to them. If you’re reliable and youre friends are good and you haven’t given your parents reasons to not trust you to go you can try convince them and lay out facts, show what coach you’re getting, that you know where you’re getting off, that you’ve got the route planned to the gig etc.
also night bus passengers can be a bit hair raising
perhaps a cheap hotel would be better?
