Sorry to hear that your young "adult" children have given you problems with DUI.....major maturity changes coming your way though
about 25 or so for girls and unfortunately about 30 or so for boys.
(no offense intended for any who visit here that might be under those ages though)

Was I suppose to mature some at 30????

Kids today do not mature at the same rate as they used to. My son's maturity kicked up quite a bit at 30 and then again at 35
