I have a neighbor whos constantly trying to wreck my sobriety,little does he know Im done with drinking and hes just making a fool of himself!
In my case he knows he will have to think about his own drinking problem,if your dad is a drinker this may be how he's feeling too.
Just dont drink,do it for yourself,nobody else.Just say no thanks and tyry aa or something if ya cant do it on your own.Its worth it!
