My grandfather taught me a valuable lesson when I was a kid this is back when black and white TVs sere common and cable didn't exist. I was running in the house and papo said don't run in the house me being a kid did not listen as all kids don't. He caught me again and said don't run in the house, I kept going. A third time he said don't run in the house. The fourth time I ran by him he stuck out his cane and tripped me I fell down and he said you see what happens when you run in the house.
