This is so ridiculous.
My daughter just got her first cellphone and she knows I get the phone at 7 each night. If she doesn’t do chores or obey house rules I take the phone away. Or any other electronic I see fit to take. Sometimes I take them all.
If your parents are paying for it, I’m sorry but it’s not really yours till you move out/take over payments.
Heck, my mom took my phone away once when I was 19 and still living at home. I was even paying my own bill since I first got a phone, plus bought all my own phones too. That didn’t stop her from taking it and there is no way I ever would have called the cops on her for it. It made me mad, but seriously, who calls the cops over that?
