Just that really.She has a day off on Friday and she wants to go into London on the Tube with 2 girlfriends and possibly 2 boys who are friends.I did let her go to Westfield a little while back with a friend but I was nervous all day.Her dad is saying an emphatic no, she is too young and I think I agree.I will be in work all day and because I work in a school I am not allowed to keep my phone on my person.I feel there is the potential for too many things to go wrong.She hasn't been on the underground by herself before and I'm worried she/they will get lost and what if they fall out and seperate?Then there's the whole crowdedness of the centre of town thing as she wants to go to Big Ben, trafalgar Sq etc.Then there's the issue of her personal safety having her Blackberry out and her camera etc, what if she were mugged?
