Gum.

The other day I was getting out of my car and thought it would be nice to dispose of my gum onto the ground. I usually never EVER litter or even spit on the ground but this seemed like a good idea at the time and enjoyed feeling reckless for half a second. Justice was served when I ended up stepping on that same gum on my way back into the car and failed to notice until it was smeared all over my car mats. Lesson learned!
