OK we have the family trip of a lifetime planned (husband, me, 12 yr old and 17yr old).....to the Far East touring a number of countries and my 17 year old has decided she wants to come back to the UK 1/2 way through to celebrate her 18th birthday with friends by going to a festival in Hungary! OK I understand she is about to become an adult and her 18th birthday is going to be a wild time for her but there is no way I am going to be able to enjoy the second half of our trip without wanting to make sure she is OK by txt/phone every day. I know I can't forbid it but I am having kittens about the whole prospect of being on the other side of the planet while she is gadding about Budapest etc with friends.....advice please!!!!
