I Think She's Lying

My coworker does this all the time. She'll stand up from her desk and tell us she's going to 'powder her nose.' Now, not that I don't believe her, but I never see her carrying any powder. The other day, when no one was in yet, I went into the women's room to have a look-see. They don't have any powder in there. You know what? I think she's lying. I don't think she IS going to powder her nose. I think she's going to take a poop.
