When a woman, sentimental to your long term feelings or not, decides to tell you a story after sex. Your reaction to this behavior is usually melancholy, followed by the call for a cab.
"I was having a great one nighter with this chick. We banged, had a nice aftermath, then she resumed to talk about her day. Storytime was at hand. I was okay with that, being a considerate fellow that I am. Then she started talking about her memoirs as a geisha in Japan a few years back, so I called a cab."
