In my bag, I have a pen that I keep handy, and a Metro-North receipt that's blank on the back.
When I think of, or encounter a randomly odd or disturbing thing, I write it down on the back of that little receipt.
Here's my list:
-People that clip their nails in public - UGH - EWWW - GROSS - leave it in the bathroom, folks!
-People that talk LOUDLY on their cellphones in quiet places, and then look at YOU rudely when you seem annoyed.
-Next3l. Ugh. Enough said.
-When the cats INSIST on using the litter box the SECOND I clean it.
-Improper comma usage.
-Calling people "troops." Um, they're HUMAN BEINGS, not some random technological term. But if you feel better saying that there are currently 3500 dead TROOPS in Iraq, than so be it. Just KNOW that a troop is a PERSON.
