Gum.

I stepped in gum at school yesterday. I almost stepped in another piece in the parking lot not 20 minutes later. It's annoying to be sure, but still better than dog poo. That said, it makes me a bit mad at people who spit their gum out on the sidewalk. I mean, who is teaching these people such lousy manners? Are these people chewing poison that they can't wait for one of the many trashcans on campus, or one of the trashcans they keep in every single classroom? Honestly, it's terribly terribly rude. I can forgive someone accidently dropping it when laughing or talking or some such, it does happen, but to intentionally just hock it wherever one is standing? Terribly poor manners. It's about as nasty as finding a loogy hocked in the stairwell in one of the main thoroughfares on campus. It's just not right.
