I was in an elevator with a half a dozen others. As the doors started to close, a woman sprinted towards us yelling “wait!” I was closest to the control panel, so I started jabbing the “Open Door” button. But to no avail: the doors slid shut unabated. Our last glimpse of the woman was of her running, reaching out, desperately trying to catch the edge of the door. I turned to the other people in the car and flashed them a “well, I tried!” smile.
