@msolga,
yes, it was in the mid 80's in toronto he was on a book tour (can't remember which one), he spoke did readings and then a Q&A, very entertaining, i wasn't actually able to go, and was supposed to meet friends afterwards, the theatre he was in was on the danforth a bit of a walk from the subway at yonge and bloor, but it was a nice night and i decided to walk as i had time before the show was to end
while crossing the bridge over the don valley, still about 20 minutes or so from my destination it started to pour rain (the sky had been cloudy,but not threatening), when i finally arrived at my destination i was soaked, and found out that thompson had been late and the talk was still in progress
the nice lady at the ticket window told me to go in an find my friends, i walked down one aisle and was going to duck down and cross at the stage, as i did thompson, who was walking around and talking, came to the foot of the stage, looked at me, looked around as if puzzled and said "you're all wet", i replied that it was raining outside, he said"best place for it" and reached down to shake my hand, best way to get noticed by your friends is to crash a lecture and get to meet the host
got to see the last of the talk and hear the Q&A
