Why I'm Tired

My dog Rexy and I watched the sunset last night.

We noticed that the sun was stalling. It seemed to be refusing to disappear behind the horizon.

I asked the sun, "What's going on?"

The sun said, "I like hanging out with you guys."

I said, "That's sweet, but we're kind of tired and we'd like to go to sleep."

The moon shouted way off from the side, "What's the holdup?"

Rexy said, "It's going to be a long night."
