Everyone's Best Friend

Sam calls everyone his best friend. There's his best friend Andy and his best friend Nate and his best friend Ivy and his best friend Zeeny and yes, even his best friend Mommy. Well, last night I had some students over and the doorbell rang. One of the other students with me said, "Oh, that's Cassie. I saw her pull up." Sam jumped up and ran to the door shouting, "My best friend Cassie?" (He'd never met her before. Ever.) Cassie, who heard what he said, asked, "Am I your best friend?" To which Sam replied, "Oh, yes!"
