I contemplate a tiny handprint on the window. Using hand signals & perhaps four words, I propose that it’s time to find out if it’s on the inside of the glass or the outside. The girl next to the handprint isn’t clear about what I’m doing. So I reach over & smear my finger across it – revealing that a child had pressed his or her hand against the inside of the glass. When I’m finished she grimaces & gestures at the handprint, still not sure what I’m saying.
