Joe Franchi, my best friend in 4th grade, was taught by his step mom not to look down while walking. I was taught to stand up straight by my grandfather but looking all around was OK.
One day on a walk with Joe I was looking down and found a $20 bill (~$100 today) in the grass along a chain link fence.
In recent years in a New Mexico café I looked up and saw hanging chili peppers.
I have lost touch with Joe Franchi and my grandfather died many years ago. Each day I try to look up and down and all around.
