“…that’s not where garbage belongs, and whoever left the cup made it someone else’s responsibility, which I thought was a cowardly way to pass the buck.”
Agreed. And this irresponsible attitude can and has grown and spread throughout culture. Too many people are contaminated by it, so it’s practically normalized. If you have ataxia or any sort of disability, you especially do NOT want to make your life feel more difficult and have less mental fortitude by carrying around a negative attitude.
Your attitude is your responsibility. Don’t wait for somebody else to take care of your garbage. I mean that both literally and metaphorically.
