Dianne- My sister got her Ps yesterday and she said she got them so that her mates had a safe method of transport. She's 18 going on 40 btw not all teenagers are irresponsible and you might be thinking "well she said that to you" or along those lines but I can guarantee most kids won't speed or drink and drive. It's the minority hun!

Also regarding roaming the streets at odd hours; maybe ask him? it will put your mind at ease hun. and have that chat with him. He'll be nice and open to ya and you won't worry (so much anyway). HTH
