Weird Tics - the strange stuff we do without realizing it

My sister pointed out the other day that I go through a physical sequence when I'm asking someone a question--I didn't notice until she pointed it out, but I realized I do this all the time. She's calling it my tell.

My hands twine behind my back.
One foot sweeps back and pops up onto the toes, such that my weight is on only the other foot.
I lean forward toward the person as I'm asking them the question, then shift back to hear their answer.

I /think/ I'm consciously aware of the other weird stuff I do, but this one surprised me to learn about because I didn't realize I was doing it, at all.
