Those Who Help
If you ever feel down about humanity, visit C's special needs swim class. There you will meet a few young people who do their jobs with great skill, respect, kindness, and patience. In fact, it will become clear to you in just a few moments that they love what they do, and that they love the kids with whom they work.
They won't get rich doing this work, but without them I don't know where kids like C would be.
