I have a question - did your teen explore the wider London area, or did they stick to their own immediate area? Our area is a little "rough" to say teh least, and I hope they (like I used to do) also hang out in other parts of London as they move through their teens, explore and make use of the city. When I was 16, I was (under age) night clubbing across London, hanging out in Camden, going to gigs all over the place, coffee shops, etc.
What has been your experience, has yours remained "local" in their choice of hunting ground, or are they out and about all over the place? And from what age did they start doing this?
Cheers!
