DS (14) wants to spend NYE with friends. I'm fine with that but I'm wondering how he gets home that night. He's not allowed to sleepover (that's a whole other story) so he'll need to come home but I don't want him walking home at 1am on his own (we live in London). DH and I would like to have a NYE drink or two so we couldn't drive to pick him up. I'm guessing taxis will be hard to come by. What do you do?
