shadows of echoes of memories of songs

I frequently have this sort of debate with a colleague who's very active in the cycling campaign. In his books cyclists are always right, and others (especially drivers) wrong. I keep maintaining that part of the role of the campaign (of which I am also a member) should be to educate cyclists on subjects such as lights at night, red lights, one way streets, pavements, and signalling as they are also part of the problem. He's much more interested in taking photos of lorries unloading on double yellow lines.
