I picked rocking/swaying, although my finger clicking is a very close second.
It's funny with the interupting thing, because as a child around my grandparents it was a lot of "speak when spoken to" and "seen and not heard", so now, in shops, at work, with friends, I tend to wait idly by until someone comes up to me, or, if I am feeling sarcastic, I raise my hand. I have a feeling that last one is a latent symbol of defiance...
I do chew the skin around my finger tips and anywhere else that needs getting to, not so much a nail biter, although I am obssessed with getting any dirt out from underneath them.
Socially I am terrible, so my boss/partner has decided to make it her mission to make me date-able. I am not amused.
Terrible at picking up the signals that NTs give off, especially the ones that mean "you can go now". That was one class I DEFINATELY missed.
My current quirk is having elastic bands in my pocket. Sometimes I put a couple on my wrists, and s**t, does it freak the easily freaked out or what? They are akin to a security blanket for when new or disliked people are around.
As I am verbally unable to express my true feelings to the object of my desires, I write them down in the form of a song. If I can't write a song, then I go into shutdown until I am done.
I do not like the saying "don't let the cat out of the bag". What the hell is that all about? Why is there a cat in a bag? And what has it done that warrants it's future incarceration? If you want me to keep something secret, either do not tell me, or tell me not to tell anyone! Do not bring cats into an already complex situation! Is this the same cat that was put amongst the pigeons? Are these pigeons the birds of a feather that stick together? How come many hands make light work, but too many cooks spoil the broth? It is not just English that is full of this pish, the Chinese have "a rolling stone gathers no moss". So what? AAAAARRRRRRGGGGHHHH!! !! !! !! !! !! !! !!
