And that's that

This afternoon, my sister Amanda stopped by to return some books she borrowed. She was only here briefly, as she was on her way to meet her husband at church. As she was leaving, she called down the hall to Sam, "Bye, Sam! Be a good boy!"

From down the hall we hear, "You be a good boy too!"

Amanda and I laughed. She said, "Sam, am I a boy?"

"Yep."

End of story. Amanda tried to tell Sam she was a girl, but he was not convinced.
