My nine-year-old son decided it would be a good idea to have a lemonade stand. He set one up in the driveway and waited for customers to arrive. He waited. And waited. And waited. Not one customer showed up.
Then he had a brilliant idea: Take the lemonade stand to the customers. He poured a cup of lemonade and walked to our neighbor's house.
"Would you like to buy some lemonade?"
The neighbor smiled and agreed to the purchase.
The boy went to the next house. Same thing. He kept going, back and forth, until he was out of lemonade.
When he came back into the house, he dumped is coin cup on the table. He had made almost ten dollars. "See, Mama? It was a good day for a lemonade stand!"
