...the fact that when you are leaving a NYC subway during the morning commute and it's pretty packed, as it always is, and you're literally a little sardine, and you're walking up the stairs to the street single file the person in front of you's ass is just INCHES FROM YOUR FACE!!!! Now I can't stop examining the person walking in front me and stopping myself from forming the mental image of my face a mere few inches from their bare naked ass! It's really gross. Think about it.
<-- It could be this guy. Sickening.
Happy subway riding!
