Hi. Ds1 was always very trustworthy when he was younger, so I allowed him at the time to have a later curfew... But now ds2 is insisting that I give him the same curfew time, but I don't really trust his friends... They haven't perhaps done anything specific, but am I justified in being concerned about what they will do? They are the kinds who I know drink alchol and one of them smokes?
