Key

I was working in one of my trailers and I was sweeping some trash into a circular trash bin that moves on wheels. I thought it'd be smart to push down the trash with my foot since the trailer is elevated off the ground by a few feet. As you can probably imagine, the trash can started to move around due to it being on wheels, and the trash bin slips away, I jump, and land on my knees. Than I get back into the trailer and fall out again.
