Good job by grandpa, good mindset.
I had a neighbor whom I didn't know (his back yard backs my backyard) come to my door at 3:00 in the morning one time. I flipped the light on and saw him through the window in the door. He said, "I'm your neighbor". Seeing only him, I opened the door and he started to speak, when he saw my one handed 870 technique and stopped midsentence. It seems that my back yard motion floodlights went on and didn't shut off and kept him awake. After introductions he left and I went and shut off the lights.
