This note is in the box of memories Mom kept for me:

I have an odd notion of what happens when a man notices that his son has started growing some facial hair. First, it would be a moment that fills the father with a feeling of accomplishment, of transition, of
pride ("My boy is becoming a man!").
The father would then load the son into the jeep and drive to the drug store where they would look over the shaving equipment. The father would point out the different kinds of razors with double-edge blades or single-edge injector blades. Maybe the father would even suggest an electric shaver, or, better, steer the kid away from ever using such a device. Then they'd consider the shaving creams. The father might explain why he prefers foam, gel, or maybe even soap and a brush.
Then the father and son would take the supplies home where the father would demonstrate good shaving technique. "Shave in the direction of the hairs' growth" (but then a kid with a little peach fuzz can't really see what direction the fuzz is growing...it's just growing
out). Maybe the father would give advice about how to deal with nicks.
And, if the father is bold, he might even take this opportunity to explain what is going on in the boy's body that is causing hair to grow in new places and, if he's really, really bold, he might even use the event as an excuse for the dreaded, full-fledged birds and bees chat.
But that's not how life is.
What really happens is the father says "Beth, show your brother how to shave."
Beth showed her brother a razor that was in the bathroom. It was designed, at least marketed, to be for a woman's legs. And a bar of soap. Jack used an electric shaver so there were no real shaving supplies on hand. I don't know if Beth actually supervised any actual shaving that day.
For years shaving was an awkward, even shameful, activity. Nicks were especially scary. They gave the world proof that I had engaged in that ungodly behavior. I think Jack sensed my shame and enjoyed pointing out that I had nicked myself.
I don't know how long I used that ladies' razor. I don't know who else might have been using it at the time. Sometime, somebody gave me a little travel razor. It was in a tiny zippered case. Its tiny handle screwed onto the head that held a double-edge blade. That thing was a godsend. I finally had my own razor! And it was small enough that I could sneak it into the bathroom where I had it perform its shameful duty. I wonder where it came from.
But you know what? I know where it is! In my box of treasures! My happy little razor:

I eventually figured out shaving on my own. And I even got over the shame.
The birds and bees chat never happened.
