What The F*@$ Is That Noise?!?!

So about a week ago I was in the office at Dinosaur Train, and my fabulous office-mate all of a sudden looked up and said, WHAT THE F@*$ IS THAT NOISE?!?!

It was my jaw. I was chewing gum.

I have TMJ, so I should never chew gum at all, but sometimes I'm tired and stressed, and it's either a pack of sugarless gum or a box of Panda Puffs. For better or worse, the sugarless gum usually wins.

Now, I've worked solely freelance (translation: all alone, unshowered, and in my pajamas) for almost ten years, so I've grown completely unaware of some of my more annoying while-I'm-writing quirks… such as chewing like a cud-lovin' cow with my jaw clicking out a fierce flamenco beat.

I also have a driving need to work barefoot… and I sometimes put my feet up on the wall. At the office I suddenly noticed there were now large black footprints on the wall next to me.

Allison Winn-Scotch had a great blog post yesterday about rituals writers like to do before they start writing.  My question is similar, but different:

When you write, do you have any have irritating habits?  Things people tend to notice and maybe not appreciate?

For example, in addition to the cacophonous gum-chewing and the nasty footprints, I've gotten complaints from strangers because I tend to act out on my face what I'm writing.  I don't even know I'm doing it, but apparently it's a little disturbing to have a shoeless weirdo in a corner of Panera making bizarro faces while she stares at her computer.  Apparently it put some people off their bagels.

So what do you think?  What are your weird quirks that serve you when you're writing alone, but might raise an eyebrow when you work in public?  Have you gotten any complaints?  If so, are you trying to work on them, or are they just part of your process and you're stickin' with 'em?
