Lou drags his feet from the door he opens and slams it shut. He trudges to his room and falls on the bed. By the sound of this, you'd know that he had a bad day.
Once he had the motivation, he went to his restroom to shower. When he closed the door behind him, he noticed something that was written in his mirror. He was about to wipe it before he saw the familiar handwriting:
"Dear Lou,
Think like a proton; always positive
From, Nolan <3
P.S.: did you know people eat snails? I guess they don't like fast food"
Lou laughed at the joke after the quote above that made him feel better.
He kept the note on the mirror and never cleaned it off, reminding him to be a proton in this dreadful world, thanks to Nolan.
