Today I did what I guess is kind of a rite of passage for most fathers: I showed my son how to shave. He's been getting a pretty serious moustache shadow. As I told him, he didn't get it from me; I didn't have to shave until I was 18 or so, and he's only 12. And even then, I was hard-pressed to need it more than once every two weeks or so.
I didn't go through any such a thing with my own dad. As with most things I've done in my life, I never asked for advice or talked about anything. When I decided that something should be done, I just did it. Which, now that I look back on it, must have made me an endless source of surprise for my parents. Heh.
