And then the fight started...

My wife and I were sitting at a table at her high school
reunion, and she kept staring at a drunken man swigging his
drink as he sat alone at a nearby table.
I asked her, "Do you know him?"
"Yes", she sighed,
"He's my old boyfriend. I understand he took to drinking
right after we split up those many years ago, and I hear he
hasn't been sober since."

"My God!" I said, "Who would think a person could go on
celebrating that long?"
And then the fight started...
