excerpt from The Color of Freedom
An elderly man with kind eyes behind rimmed glasses sat behind a computer. “Hello, son,” he greeted Andre. “How can I help you?”
“Well, I’ve come to buy the blue 1976 Ford Ranchero that has been sitting right there for the past few months,” Andre explained, pointing to the empty spot on the lot.
“Oh,” the man said, frowning. “Well, I’m sorry, but someone else just bought that car this morning.”
Andre’s heart sank. While he had been painting Mrs. Robinson’s kitchen, someone else had casually driven off with his car. All his hard work had been for nothing. Tears began to form in his eyes at the thought of riding the bus home.
Seeing the disappointment in Andre’s face, the man said, “You know, we have quite a few cars for sale in the back lot.”
“Well, I—” Andre started.
“They are priced about the same as the Ranchero was. I’m happy to show them to you.”
