I have been thinking about starting such a thread for a while, this is for strange cycle/transport related things you have overheard other people talking about. The break room at my work is a rich source.
Yesterday it was:
Girl - I sometimes feel a bit guilty about using the disabled parking space.
Girls friends - *general noises denoting slight embarrassment*
Girl - But if I'm only there for 40 minutes or so it's okay.
Then another time:
Girl - OH MY GOD, how on earth do you manage without a caar????!!!!
Boy - I just ride my bike.
Girl - Oh. Yes.
