A horses hair in the wind

I had a thought about breakfast. It lasted five seconds and then it cried itself to sleep.

My brain tried to remember my password. It forgot and got a restraining order.

He had a thought about winning. It was like a kid who thinks he's gonna be a superhero but ends up being a sidekick.

She had a brain fart about pizza. It didn't even make it to the crust.

He thought about getting a tattoo. It quit halfway through the word 'cool'.

My thought about life was interrupted by a sneeze.

My thought about the weather was 'meh' and that's it.

He had a thought about fame. It was like a ghost that didn't even know it was dead.

She thought about changing her life. It took a nap and left.
