I don't get it. Do people give you shit for not drinking when you go to events? I've never had any problem when I decide I don't feel like drinking that day. You say you don't want to tell people what to do, but you want them to stop drinking?
I'm old and stubborn enough now to know that if I don't want to do something, being outside of the crowd is no big deal. But it's still something that occurs, and some people are particularly sensitive to the effects of going against the flow or find it very difficult to do that.
