potentialities

When I was a kid I was obsessed with those round stools all libraries seem to have in the stacks. You know, the ones that have little castors inside them so they can be swivelled around and kicked along easily? They have a spring inside them so that when you step on them the stool's body drops onto the floor.

I remember kicking these stools around like crazy. Another popular game was to jump on and off the stool to play with the springiness.

I am sure that I would have been told off in your library... :)
