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.
I smell everything. Dog’s noggin, the insides of books, my morning cup of tea. Everything gets a healthy whiff.
When I’m in the shower, I purse my lips and blow directly against the water coming down because it makes a nice sound.
When I’m reading, I rub the edges of the page I’m currently on super tightly between my thumb and index finger because I like the sound and the feeling. I also rub the tops of my nails when I’m wearing nail polish for the same reason.
