I climbed on a rock at work to reach the plate of fruit to replace it with fresh fruit for the butterflies and I slipped off the rock and got a chunk torn out of my hand from the fall.
After I got up (my first thought was "OH MY GOD I HAVE TO SAVE THE FRUIT" for some reason) and reported the accident, cleaned myself up and prepared more fruit I went to put the plate back and realized I could have reached it without climbing on the rock.
I still have the scar on my hand
