First day of the season about ten years ago at Killington, you know, like September 12th or so

, I was coming up on this guy on his left. I didn't have my ski brain wired all they way quite yet, so I yelled "On you right" - as I passed him on his left. Realizing my idiocy, I yelled back after I passed him, laughing, "On your OTHER right", then stopped.
We shared a laugh at the knoll, and he said that he heard me on his left, and when my words didn't make sense he said "I decided to stay the course, hoping you'd figure it out".
So, maybe his pet peeve is skiers who don't know their left from their right !
