If I'm not mistaken it was at my 10 year wedding anniversary, so that would be at age 31.
We celebrated with family and (JW) friends at our place.
Drank beers and (spiked) sangria from 8pm til 3am when all (but one) friends had left. That wasn't even the real issue. I was just buzzing a little bit.
Then the one friend who was left - and stayed at our home for what was left of the night - said, while already on his way to bed: "Too bad there aren't any beers left."
We still had 3 quarters of a bottle of the gin that was used to spike the sangria, so I told him jokingly "we can finish that bottle ;-)"
"You know you must never dare me"
"I dare you"
15 minutes later that bottle was empty, and soon after my bedroom changed into a fast spinning carnival ride.
I'll skip some details. Rest assured that shortly before passing out I managed to quickly push my meeting shoes out of harm's way.
When I woke up it was 3pm, and I was not feeling well. Unfortunately it was Sunday, and I was scheduled to read the Watchtower.
I had to call in sick. "Guess I'm coming down with the flu or something. Headache, feverish chills, nausea...."
No more gin for me. (Not that that helped me when German police took me in custody years later ;-)
