I can relate to this... I can totally relate to this. Family functions, work events and weddings I just don't drink, because I can't get drunk like I want to.
I can actually take this even further >
In the past I have told all my friends I "quit", and would go to parties or events with them, and drink in secret. In closets, bathrooms, alley ways. They were usually so hammered they had no idea, but were always amazed at what a fun guy I was sober.
So much dishonetsy is associated with alcoholism. It's weird.
