Disclaimer: I'm not a parent, but don't have a decent parent to discuss this with and also this all happened before coronavirus.
My friend and I are both 17, her parents are what I consider to be incredibly strict, but she thinks they're just responsible-- not that I ever question or tease her about it, I like her parents and it's hardly my place to say anything.
She has an app on her phone so that her parents can track her location all the time, if we go anywhere but the places we specified (e.g. We went ice skating, and then went to the supermarket next-door for sweets) her parents call her right away and say she has to come home.
I think that at the age of 17 that's a lot, considering she's independent and really well organised, never ever gets in trouble, never goes to parties, or does anything even remotely dangerous.
Opinions?
