A short story and a confession

Graham liked to tell people that they were wrong.
This made Graham feel smart.

Graham used to tell religious people that there was no God.
Graham used to tell desperate people that their "alternative remedies" would not work.
Graham used to tell optimistic people that positive thinking is futile.
Graham used to tell trusting people that they were naive.

When Graham said that people were wrong, he was usually right.
But secretly, Graham used to cry himself to sleep at night.
Maybe Graham wasn't so smart after all.
