I used to live in Downtown San Jose, way back in the late 70's, before it was rehabilitated. We used to refer to it as the "wine country" for all the drunks and winos.
One afternoon I'm napping in my (ground-floor) apartment and someone tries to break in by smashing one of the small panes in the window directly over the bed where I'm sleeping. When he reached in through the broken window to undo the latch I just grabbed his hand and ran his wrist along the broken glass left in the frame.
He vanished . . .
