The village where my mother was born, had no water, almost no electricity, and no cash, back in 1970. It was barter. My mother told an anecdote of some entertainer with puppets that went around the villages. Kids wanted to see it but had no money, so they gave him eggs. Till the man had so many eggs that he exploded and said he wanted no more eggs! What could he do with dozens of eggs on the road?
