Recently, I read a story about fish suppliers who were having problems shipping codfish from the East Coast. By the time the fish reached the West coast, they were spoiled. They froze them, but by the time the fish arrived, they were mushy. They decided to send them alive. But the fish arrived dead so they tried sending the fish alive again, but with one difference. They included a catfish in each tank. By the time the codfish arrived, they were alive and well. Apparently, spending the entire trip fleeing the catfish had kept them alive and well.
We all have catfish in our lives. Typically, we complain about them. Maybe we should be thankful. They may be keeping us alive!
