I don't thank or speak to my bike. I don't give it pats of affection, either.
But I do feel some sort of affection for my bike. I guess I feel some sort of affection for my car as well. Even though I really hate driving. But I admire a faithful machine. Both the bike and the car are very ordinary. Nothing special at all.
I can think of one car and one pickup truck from my past that I kinda miss- a 1974 Plymouth Valiant and a 1974 Dodge 3/4 ton pickup. Both very ugly-ducklings, yet very lovable. Even though they were quirky.
I can't think of any bicycles that I really miss. Even 'better' bikes than the types I ride these days. Once they die I just get another one and the old bike doesn't matter any more.
