3 1/2 stars. A short flirtation leads to a steamy encounter when near strangers Caitlin and Mark are locked in at the subway exit overnight. Dialogue is the star of this short story; the two have the sort of sharp, zingy conversations that everyone would wish to have on an unexpected "first date." Their give-and-take is so smooth and companionable that the possibility of real romance coming from this odd encounter doesn't seem too implausible. Except that one of them is Caitlin. Whenever she's talking to Mark, I liked her fine, but whenever she's in her own head she rubbed me the wrong way. She uses words like "lady parts" -- yeech -- and one minute she's daydreaming about marrying her boyfriend (whom she later says she didn't even like) and the next she's all about Mark. I felt like she needed to go to a Sex and Love Addicts meeting a lot more than she needed to start a new relationship.
