A jumping mobile phone. It apparently jumped of its own accord.
Okay, I’ll come clean. I didn’t see it jump. It was on the window-ledge behind me. What I did see, however, was its entrance into my field of view, at which point it was moving far faster than one would expect of a stationary object. There was a whole bunch of other stuff on the window ledge and none of it was disturbed. The only two people within touching range of it were me and someone else who was paying it as much attention as I (i.e. none).
WHERE IS YOUR GOD NOW, ATHEISTS?
