Funny you should mention this, because I feel the same way. Hypocritical...
I have never been one to go out and tear it up very often. I used to like to do that every once in a while, but the older I get, the more it just seems stupid. Right now, I am going to college full time and working, and with kids it just doesn't seem like I have the time, which doesn't bother me.
I don't like to go out with the A though, because I end up being forced into the "mom" role. You know, I can't drink because someone has to make sure he gets home, someone has to drive us, etc. Which is why I don't go out with him much because that's no fun.
So yes, I do find myself feeling hypocritical at times when someone invites me to go out and have a few drinks.
