My daughter can’t stand litter.
We drive by litter, and she complains about it. We walk by litter, and she yells at the people who she imagines have left it behind. She looks at litter and makes grunts of disgust.
But unlike so many people, she actually takes a stand against litter by picking it up and throwing it away whenever she can.
Sometimes, she will actually stop whatever fun thing she is doing just to rid the world of a stray can or a scrap of paper.
I love this about her.
