Not drinking does not equal not socializing or going out? You can go out to eat with friends without ordering a glass of wine...

You missed the part where it loosen up. Some people are shy and a drink help them speak up in groups. The younger me felt that way.

The trick there is that when everyone else is drinking they'll be making huge social gaffes almost continually. Makes it much easier (for me at least) to relax and not worry so much.
