I thought that this passage from Zen and the Art of Motorcycle Maintenance might have appealed to Grandpa: I care about these moldy old riding gloves. I smile at them flying through the breeze beside me because they have been there for so many years and are so old and so tired and so rotten there is something kind of humorous about them. They have become filled with oil and sweat and dirt and spattered bugs and now when I set them down flat on a table, even when they are not cold, they won't stay flat. They've got a memory of their own. They cost only three dollars and have been restitched so many times it is getting impossible to repair them, yet I take a lot of time and pains to do it anyway because I can't imagine any new pair taking their place. That is impractical, but practicality isn't the whole thing with gloves or with anything else. The machine itself receives some of the same feelings. With over 27,000 on it it's getting to be something of a high-miler, an old-timer, although there are plenty of older ones running. But over the miles, and I think most cyclists will agree with this, you pick up certain feelings about an individual machine that are unique for that one individual machine and no other. A friend who owns a cycle of the same make, model and even same year brought it over for repair, and when I test rode it afterward it was hard to believe it had come from the same factory years ago. You could see that long ago it had settled into its own kind of feel and ride and sound, completely different from mine. No worse, but different. I suppose you could call that a personality. Each machine has its own, unique personality which probably could be defined as the intuitive sum total of everything you know and feel about it. This personality constantly changes, usually for the worse, but sometimes surprisingly for the better, and it is this personality that is the real object of motorcycle maintenance. The new ones start out as good-looking strangers and, depending on how they are treated, or else can turn into healthy, good-natured, long-lasting friends.
