Reunion Joke

My wife and I were sitting at a table at my high
school reunion, and I kept staring at a drunken
woman swigging her drink, as she sat alone at a
nearby table. My wife asks, 'Do you know her?'
'Yes', I sighed. 'She's my old girlfriend. I understand
she started drinking right after we split up those
many years ago, and I hear she hasn't been sober
since.' 'My Gosh' says my wife. 'Who would think
a person could go on celebrating that long.'
