One thing you of which you must be more vigilant is hair growth on the outside of your body, which cannot be covered up. (Well, I suppose you could wear ear muffs wherever you as if you were some discarded Peanuts character, but you might look silly in, say, San Diego.)
I remember being in fifth grade and seeing a forest of nose hair for the first time. It was of a theatre teacher that our class worked with. He was tall (but then we were 10, he may have been 5’5”), with coarse strawberry blond hair on his head, and more inside his nose, his nostrils turned upward displaying the follicles as if upon a pedestal at an art exhibit.
Now, as I grow older, I see hair on the outside of the nose, breaking through the pores, from the bridge to the nostrils. A friend in the medical profession once told me, “Any cell can grow hair.”
I monitor it because it is important to me — I have enough hair elsewhere — and so I pluck it. This hair is surprisingly resilient, firmly rooted in the roots of my bridge or even in my ear canal. I swear I once had an ear hair that was sooooooo long — how long was it? — it began in the other ear.
Some people do not prioritize this grooming practice as much. Or maybe they have other, more pressing needs in their lives, or perhaps they’re forgetful and the second they think about it, their minds shift to other topics.
But it becomes frustrating to you, on their behalf. Do you mention anything to him? There you sit, engrossed in conversation with him, but there it is, on the bridge of his nose, shaped like a rainbow, just pointing at you — a jet black hair. You cannot help but reach across the table and yank it right off the tip of their nose. “He’ll thank me,” you believe. Or a perfectly groomed eyebrow with one rogue hair protruding in an opposite direction from the rest. A rebel! Just give me two seconds and that sucker won’t bother you (or me) anymore.
It can be very distracting.
As you enter adult puberty, you become more attuned with this type of cell mutiny. Not just for you, but for all mankind.
