Stupid f***ing lunatic

As I was cycling into work this morning along a dangerously ice-encrusted cycle path, I observed coming in the opposite direction a gnarled old man wearing a filthy coat and hat and struggling along the same cycle path on a wobbly bicycle from the 1850s. On the same side of the road as me.

i.e. From his point of view, the wrong side of the road.

As this rather disturbing Ealing-comedy-inspired character neared me, he clambered down from his machine and proceeded to push it past me, muttering with a distinctly Scottish accent, "Stupid fucking lunatic".

I have a feeling that at least one of us was confused.
