My aunt and uncle docked allowances and took away dessert when we were little. When we were older and were grounded, they either wouldn’t drive us anywhere, or took away keys to the car. When my cousin Malky had a job, he was allowed to go to his job when he was grounded, because it was an obligation, but my uncle drove him there and picked him up, so he couldn’t go anywhere else. Then, if he got a paycheck while he was grounded, they held onto it until his grounding was over.
I only got grounded once, but another time, when I seriously screwed up in school, and got a “smoke-up,” or a notice of a potentially failing grade in PE (because of my attitude) I had to do exercises every morning until my grade came back up.
They (my aunt and uncle) had all the power, and we knew it. They were kind people, who took good care of us, and only threw their weight around when it was necessary. But no one ever considered anything like trying to take the car keys during a grounding, because they would report the car as stolen. At least, that’s what we speculated they’d do, and believed they would do.
We behaved ourselves as teenagers (mostly-- Malky was a handful), because we believed in their authority, which they had spent our lives establishing. On top of that, though, we loved and respected them, and really, when all was said and done, did not want to disappoint them.
Someone who is just starting to lay the foundation when the kid is already 14 has a lot of work. It’s not impossible, but it’s going to be really, really hard.
