When I quit drinking (the first time), my "friends" would call me up and say, "Hey, let's go to ____" and I'd say, "I can't. I quit drinking." I cannot tell you how many people just could not process that. Every single one of them responded in all sincerity, "WHY?"
The moral? Those who I partied with who were still drinking (which was all of them), had NO THOUGHT that I should stop drinking. They'd literally shake their heads and walk away from me when I told them I was sober. Never-effing-mind the fact that I could have killed myself or worse someone else, drinking and driving and passing out at the wheel every weekend. Throwing up all over myself every other night. Waking up with black eyes and no memory of how I got them. Screaming and yelling at people and terrifying my cats. And all the other **** that was my life back then. They were clueless. And most of them? Still drinking.
