Writers are observers

I think that writers are naturally observers. We drink in the world around us.

For example, I noticed that when the clerk at the convenience store talks, none of her teeth show.  And I noticed that a co-worker shuffles when he walks.

Of course, being a writer, I file all this great stuff away for later use. Here are some recent observations about people in my world:

--picks at cuticles and makes them bleed

--always chewing gum

--wears ring on thumb

--scrapes bottom lip with front teeth

--voice drops at end of sentences

What about you? Do you collect mannerisms and movements like baseball cards, filing them away until you need them?
