What's the protocol when some dozy bitch walks out in front of you as you're pedalling in a leisurely fashion along the canal, trying not to look like you're about to keel over? My bike (ew, that still sounds wrong) hasn't got a bell. Do I shout "ding ding!"? "Beep beep" would just seem inappropriate. I can't shake my fist, I'm still new enough to this cycling lark to go arse over tit. Shouting some abuse might be an option if I learned to pedal a little faster, but at the moment I think I'd end up trying to make my getaway on foot, after throwing the bike at them.
