One of mine is when I finish wrapping my hair up tightly in the towel to dry after washing, I whack the towel where it’s tucked in, kind of like encouragement to stay tucked for the duration, kinda like a coach does when sending the kids onto the playing field.
Yep that’s exactly the thought process behind it lol. I’ve walked into and out of a couple interviews doing this because the alternative is usually the hand recoil plus an “ow fuck”.
