An old artist set up his easel and canvas in the park. A small crowd soon gathered to watch a master at work. Suddenly a young boy piped up, "I think he's doing it wrong."
The crowd murmured and scolded the boy, but the master asked the boy, "Son, WHY do you think I'm doing it wrong?"
The boy answered, "My father is a shoemaker. Your shoes are too small for your feet."
The artist smiled and said, "You know son, I think you're right. I never would have noticed if you hadn't mentioned, but you're right: they do pinch a bit. I'll buy new shoes from your father's shop today."
No one is a master at everything. Learning comes from all places in all ways.
