Well I'm not going to be able to get that image out of my mind for a while.
*shivers in a corner.
Well... if you really want an image, we took photographs. Every so often I will light one up with someone else around - and when they get a funny look, I show them the "after" pic, with the dead spider and the hundreds(thousands?) of dust motes for 2' around it... except they're not dust motes. Yuck.
Regarding the OP, I often lent my pocketknife(I started carrying it because being part of the stage crew was difficult without certain tools) to my high-school teachers, or helped to open packages. Of course, this was back in the old days... ten years ago.
I am often floored by the amount of change which has taken place in my own short lifetime.
