I try to do random acts of kindness. Sometimes I don't succeed. Sometimes, I succeed even when I don't mean to.
The day of the seminar I apparently performed a random act of kindness. As we were leaving I asked someone I knew if they noticed he never mentioned his son. One of the ladies said "maybe he's gay". I said "there are worse things to be" (which I still don't like because it implies that I think there is something wrong with being gay). Unbeknownst to me, one of the ladies in the group has a son who is gay and she hasn't told anyone. I didn't know her son was gay.
She called my coworker to ask if I knew her son was gay. She thought I was sticking up for her. I made her feel better for saying what I said.
You never know when something you say is going to be just the thing someone else needs to hear.
