What are the odd little tics that you’ve noticed about yourself in dealing with socializing and interactions with other people?

I’ve noticed that at work, anytime I’m walking in the halls and another person is walking towards me, I look at my watch to see what time it is.

I can’t seem to control the impulse, and I guess it’s just my brain’s way of dealing with that awkward feeling of “what should I say or do here?”

Anyone have anything similar?
