If you don’t drink alcohol, then drink what you like to drink (soda, juice, etc.) and don’t worry about it. I know it feels awkward to be around folks the ARE drinking and not partake in the festivities, and at some point , as time goes by and as the crowd gets looser, it’s probably time to go. Not fun hanging out with folks stumbling and acting a damn fool. Fortunately for me, it’s drugs that I can’t stick around for.
