I also tend to wear some sort of jewelry I can play with, like a necklace or ring, to play with if I'm anxious, so I don't end up playing with my hair instead (or my wedding ring). Though I often end up playing with my hair anyway...interestingly, I don't tend to do that with T. It's more just playing with my hands or whatever jewelry I have on. So it's probably a subconscious flirty thing...
