What It Was Like Growing Up With My Father, George Carlin
Here is a bit of it:
"He taught me
how to ride a bike, with and without training wheels. He took the time to make sure I was understanding the big things that were going on in culture. I have a vivid memory of him waking me up during the moon landing and making sure that I understood exactly what was happening. I was only five at the time but he wanted me to know that this wasn’t a TV show. This was really happening on the moon. He loved sharing those kinds of moments with me.
This won’t come as a surprise to anyone familiar with his work but as a dad, he really was unafraid of expressing the truth of what was going on in the world. He always was making sure that I understood America’s history and the fact that America didn’t always treat people well. He wanted me to understand the history of oppression of black people, Native Americans, and other disenfranchised communities."
