The time: 1:30 a.m., Monday, President’s Day. The scene: The F train platform at Houston and Second Avenue.

Three attractive young women are looking on as a man jumps off the platform and onto the track. I look on, wondering if he’s crazy, or if he robbed one of them. 

A minute later, he climbs back up, says a few words to them and walks down the platform. I ask them what he was doing. 

“I lost my cell phone,” one of the women tells me. 

“So he risked his life to retrieve ... your cell phone?” I ask. 

“Yeah,” another says. “We were standing here wondering whether it was worth getting it.”

“How much is it worth?” “About $50.”
