Christmas time conflicts.
Dad called me to see about bringing the family over to his house on Saturday.
"What time?" I asked
"How about 11:00," he said.
"AM?" I clarified. "You want us there at 11:00AM on Saturday, which is Christmas Eve?"
"Yeah. That okay?"
"Um, you realize, of course, that you're planning this get-together precisely in the middle of my traditionally most-productive Christmas-shopping time?"
"It's only funny because it's true."
