I was on a multi-use trail a couple of weeks ago enjoying a gentle ride on a beautiful summer's evening when I came up behind a young couple having a romantic walk. I called out "Passing on your left", and of course, the girl stepped to the left.
I wasn't going fast so there was no problem and as soon as she realized what she'd done, she gave me a big smile and said "Oh, I'm sorry". She was kind of a cutey so I simply returned the smile and called "No problem". That must have threatened the boyfriend because he glowered at me and yelled "You're supposed to pass on the right, a-hole!".
Ever get the feeling we just can't win?
