STFU

Marcus stared into his mirror.

"I think I should get a haircut," he said.

"He thinks that he should get a haircut, he says!" His reflection in the mirror chimed.

"Huh?" Marcus turned around to see who was talking to him.

"Huh, he says!" His reflection made his jump.

"Wow, cool. My reflection could talk!" Marcus was delighted.

"It's cool that I can talk, he says!" His reflection sounded sarcastic.

So Marcus and his reflection talked for a while, each time the reflection replied in 'he says' voice.

"I'm sick of this."

"He's sick of this, he says!"

"Shut up."

"Shut up, he says!"

"Go away."

"Go away!"

So Marcus left and his reflection was no more.
