I need to keep my middle finger in my pocket

A friend of mine was really hauling *** on his bicycle. He is a competitive rider. One day a lady that was following pulls up to pass and yells something to him. At the next red light, my buddy rips her good with language I don't care to repeat. As it turns out, she wasn't giving him ****, but rather complimenting him on how fast he was moving.
That’s not just a Canadian thing. Bicycle riders seem to have some of the worst attitudes on the road – they curse at drivers while riding down the middle of traffic lanes, running through stop signs/lights, turning in front of cars suddenly with no signal, riding at night with dark clothes and no lights, etc. and anytime they’ve got a story about a near-miss or accident, it’s always some other idiots fault. Anytime I’m driving I give them a wide berth.
