look at it from the point of view of a roadie..
the sun shine out of thier ****, they are an elite section of society, smarter, fitter, more handsome and richer than anyone else. They are simply better than the rest of us, we are not fit to wipe the shite from thier shorts.
Then all of a sudden, a peasant passes them by on a bloody moutain bike of all things...its no wonder they are offended. How dare you. Even if you stopped to offer him your wife for the night he still would see your entire life as a blight upon society..
road bikers are just better than us...and thats a fact we cannot change. Dont make eye contact, dont nod and for christs sake, dont wave....thier compact, light-weight, earodymanic brains are not programmed to accept pleasantries from the lower classes. Just smile awkwardly, bow and say sorry...sorry...sorry, as you pass them.
