So I'm out today on the cafe, ditty-bopping along, and a Harley guy comes in behind me. He's a ways back as I'm coming to a stop light. I'm waiting at the stop light and I hear the Harley come up to what sounds like pretty damn close. I don't take my eyes off the light and the cross traffic because the light should turn green any moment.
A split second before the light turns I hear him say something. I couldn't quite make it out, but whatever it was wasn't said with an attitude - I even think I heard the word "please."
Anyway, the light turned and I was more concerned with traffic than with whatever it was he said, and whatever he said, he said it just as the light turned, so my mind was on traffic and I took off and he stayed at the light (not sure why he sat through a green light...).
I went slow, and later pulled over at a pub in case he was trying to ask me something about my bike (plus, I was thinking about getting a beer), but he eventually just rode by and we gave each other that 'howdy-doo' motorcycle nod and that was that.
As best as I can make out what he said, I think it was "Can you move up please?" I'm confused as hell why he would want me to move up, because I was right where I should have been - behind the white line. And you shouldn't pull up close to anyone and then ask
them to move.

So what should I have done?
