I've been encouraging one of my chiropractors to go sly. He clippers pretty short anyway.
Well today, he was almost bald. Said he clippered his head to the normal #2, then trimmed his beard without the guard, as he usually does. But noticed he missed a spot on his head in the back. Without thinking, he used the clipper/no guard to catch that one spot. And how he was nearly bald in one big patch in the back. So the rest of his head got clippered no guard. Looks great. Encouraged him to go sly. He's still a little hesitant, but likes the extreme short buzz. I'll keep working on him.
Maybe it wasn't a mistake....maybe it was a subconscious desire coming out.
Or, to paraphrase Freud, ".....and sometimes a cigar is something else."
