I have advised total strangers to zip up their zippers. The first was a middle-aged woman in the elevator at my shrink's office. She made such a production out of zipping it up and was so obvious and nonchalant that I really regretted all the quiet secret code hand gestures I cycled through to communicate this information. She probably thinks I'm an uptight WASP. Which is true. Sort of. I'm uptight about certain things, like I won't date a guy who doesn't have a strong handshake but I'm also OK with that guy Frenching other guys and wearing eyeliner. The second was a guy on the N train. I've seen him before. His shoes always coordinate with his outfits. Not coordinate as in black shoes with black suit and brown shoes with brown suit. GET YOUR FUCKING HEAD ON, SON. He will wear a lavender and cream colored suit and the shoes will be lavender and cream colored loafers. I think he shares bloodlines with Morris Day and Aresnio. So I looked at him and silently gestured and he gave me a flirty smile, like "Yeah baby, I know you're looking at me. You think I'm hot." I gestured again and he finally got with the program. After that I felt really bad for him. I almost wanted to get off at Port Authority and offer him a consolation BJer but then I remembered my policy about not giving BJers to guys with bad shoes that I meet on the subway.
