Re: Parent use findmyiphone to track me
OP, you say your siblings are over 21 but you don't say how old you are. You could be 19 or you could be 11 (my older sister is ten years older than me) and there is a world of difference between 11 and 19. Heck I know some 21 year old kids who are completely untrustworthy. Being considered an adult is not the same thing as being an adult.
Let's get one thing straight....privacy, when it comes to parent/children relationships, is earned.
If my daughter is acting irresponsibly and her friends are boy crazy and smoking and drinking, I'm not going to trust her her judgement as much as if she showed herself to be reliable, responsible, no drinking or drugs, and friends who are the same way. So I'm comfortable with giving her certain freedoms.
That said...a year or so ago, in Santa Barbara, there was a mass shooter. One parent found out her daughter had been killed through the use of the very feature you want to turn off. Imagine if that daughter had not been killed and her parents had been able to learn that they could have helped her through the use of that feature.
While the world remains a good place filled with good people, there are times when that's not the case. Or there are times when this feature is useful if you go out hiking and get lost. (A family who was lost was tracked in the snow with this feature.)
Sometimes, as young people, we rebel thinking our parents are being nosy. Then we find ourselves doing the same with our own children and we find out parents are simply trying to keep kids safe. They're not being nosy. They're trying to keep you from lapses in judgement that you may not have learned necessary life skills yet. Or they may be trying to keep you safe in a sometimes unsafe world.
Talk to them. If you're mature you may be pleased with what you hear from them. But if you sound as whiny as you do in this thread, you may not.
