Nervous Tics

The apple may fall a few generations from the tree but it's always there.

Wild Bill had this annoying tic of clamping his tongue between his teeth. I try to keep it private but yes, I do it. It helps me concentrate. Once I divulged this info to my parents, my father walked around doing an amazing imitation.

One of my friends splays her hand in front of her stomach or on her rear -- as if the world can't see what's behind the five fingers. It helps her feel covered. It's a tic.

Someone in this family turns every question back to the questioner. A tic perhaps?
