I do hear what your saying about raising a black teen.. for now I don't have one but if I do I will be proceed with caution
When I was 15 I went to a big out of town event with three of my close friends. I know all our parents had massive reservations about this particular event but we went together, dropped off by one DF and clear instructions about time we needed to leave to get home safely (this is all pre mobile phones). We had all been to events before.
The event ran late, we stayed just a bit too long, missed connections and ended up stuck at Kings Cross at 2.30am. It wasn't a nice place to be. The other three were all thinking of staying the night there rather than phoning home - their parents were not unreasonable but they were nervous of the response. I was nervous too because I'd screwed up but it never occurred to me for a second not to call. My Dad came out and got us, we stayed the night at my place whilst my Mum rang the other parents. My Dad had to work the next morning.
Looking back, we had been mostly sensible - we were not drunk, we didn't take drugs, we didn't accept 'help' from dubious people because we had learned self worth and risk management by then. We made one stupid mistake.
My Dad never shouted at me or got angry - he didn't need to I was mortified and getting it wrong. But he did tell me how relieved he was when I called - there is no degree of anger which could have made me feel worse and make me realise just how much I was loved. When I spoke at my wedding I talked about that night and how that love and security and trust had empowered me so much.
I'm in my 50s, my own children are now all in their 20s and that night is vivid in my memory. At difficult times when they were teens I tried to keep in mind that I wanted to be that parent they would call no matter what they had done and that they would be self confident enough and experienced enough to keep themselves safe until I could get there.
