I think that could make people uncomfortable and there's no need to out yourself at work to prove you're cool with who you were.
I couldn't possibly joke about being an alcoholic, unless I was still actively in denial and actually believed I was beyond it.
There's no humor in the disease part of it.
But certainly, laugh at your stupid younger drunk self who got in to absurd situations.. before it got serious.. or poke fun at yourself here and in the rooms about the insane stuff alcoholics do.
I remember this one guy talking about when you start picking up empty beer cans to see if there's anything left and you find a little bit of beer in one and so you drink you, and end up swallowing cigarette ash. That made me laugh, because I've done that. Everyone in the room laughed. But to others, that's just weird.
So I guess that's why I like AA meetings.
