About boundaries for 15 yr old bot going out times getting home how much freedom etc.Ds is 15 lovely boy lovely friends no trouble at all.he has been to a few parties where we pick him up etc.tonight he wanted to go to a freinds til midnight just to watch dvds etc.I said ok and dad will pick you up.he wanted to get a cab I said no it descended into huge row.he has gone and dp will pick him up but i think we need to set some rules now as things are changing and if i'm honest some of his friends a lot freer than him but also a lot more together in many ways too!he says we are over protective but I am more worried about something happening en route rather than drink drugs etc.i know they will prob have some cider and prob smoke but I do need to chill.How do you know when its safe to let them go?We do all the ferrying around as the otehr parents seem to have let go a bit now
