Mikey headed to the shower, feeling tired and annoyed. He couldn't shake the feeling his brother Jon was playing some sort of prank on him. It was more the sort of thing Mikey himself would do to Jon,to be honest.
Mikey, at that moment at least, had better things to do than prank his brother. He headed toward the shower. As he showered, he let his mind drift back to the half-remembered dream. He didn't pay much attention to the act of showering, and thus didn't notice as he reached for Jon's shampoo as opposed to the Tear-Free Kids Shampoo Mikey still used.
He got out of the shower and took Jon's towel off the towel rack instead of his own. Finally, he used Jon's toothbrush to brush his teeth.
After Mikey was done using the bathroom, he went back to his bedroom to get dressed.
