Judging others too quickly without all the facts can lead to problems.
I was 8 years old when I told my dad that we were making fun of this kid in school. When the teacher asked us what our dad's job was, he said, “He sells rags.” We laughed so hard we almost fell down. This poor kid had the bad timing to follow the other kids who said their dad was a cop, a fireman or a doctor.
My dad said, “Don't laugh too hard. You'll learn as you grow up not to judge too quickly. I know your classmate's dad, and he's the one who drives around in a brand new Cadillac. He makes a mountain of money selling those 'rags' that all the rest of us need so badly. So, his dad is laughing all the way to the bank.”
