Usually, it's something like "Hey, cool!" or "That's fucked up"
Talking, of course, about the unicycle(which still doesn't have a name. Should I name it?). I much prefer the large wheel to my old(read: stolen) 24 inch, because it commands a certain degree of respect. The smaller the wheel, the quicker people are to jump to 'clown'. Riding a giant wheel around town appears to be at least slightly awe-inspiring, judging from the reactions of the general populace.
About 15 minutes ago, however, I got a different reaction. I was almost done with the 'town centre' stretch of my trip - about 100 metres from a certain toasted sandwich shop - when an elderly(eh, about 55-65, I'd say) yelled "Hey!" at me.
I turn my head, because he could be telling me something important, or nice. Instead, he follows up with "get off there, ya stupid bitch!"
Naturally, I ignore him and cycle on. I don't really understand why he yelled it, though. I only have one wheel, so am technically a pedestrian - there's nothing illegal about riding on the pavement, like I was. And it's not like I'm a danger to others - it's been over a year since I actually hit someone, and that was on a rainy day. And I only just grazed her handbag.
But he must have been really angry to yell an obscenity in public, on a crowded street. So what I was doing must have been really offensive to him.
Still, I can't stay too mad or bothered about the situation. Because he said 'bitch' and not 'bastard'.
