My girls are 11 and 15. Niether of them can leave the house without me knowing where they are going and who the are going wtih . My 15 year old whenever she goes somewhere it usually requires a subway ride. My son does not go out very often. He'll stay out after school sometimes but once he's home he doesnt go out that often. He's 17. Yesterday his friend showed up and my son said going out ma be back later. I didnt ask him where he was going I just said okay. My dd got upset that it didnt dawn on me to ask him. The thing is i compeltely trust him. I knew he would be somewhere in the neigborhood. I knew it was just to hang out. It was also in the middle of the day. Then she was upset that I didnt give him a "curfew" But again i know my son. He would (and was) home by 7:30 8 the latest.
