I'm usually pretty balanced, but last night, as I was playing knight in shining hi-vis for two damsels in distress on CS3, I slowed down to offer my help. As I was stopping I caught my front wheel on a small bit of raised brickwork and down I went, still clipped in! Definitely not one of my most balanced moments.
Their look of consternation might have been concern for my physical wellbeing. On the other hand, it might have been concern for my mental wellbeing. They did look a bit ''Uh oh, I think we've got a nutter here!''
(Oh, my body's too long for my legs. And my nose points somewhere off to the left, à la Stephen Fry.)
