I like to watch people sit on the park benches.

I enjoy watching them slow down after a long run, or decide to take a break and eat lunch.  I enjoy observing their eyes glance at the closest bench to rest on.  It makes me satisfied.

Satisfied to watch them approach the bench.

Satisfied to watch them swipe off some crumbs and sit down.

Satisfied to watch their faces turn from relieved to scared.

Satisfied as the bench explodes and all of their limbs fly everywhere.

Because that's how I lost my limbs.  And that's how I am slowly gaining my revenge.
