Best friend

“*You are in class with your best friend sitting next to you. You decide to play a silly addition account prank until class starts. You ask him what 2+2 is.* *He looks at you laughing and puts his arm on the chair to support himself, looking into your eyes with a sly smile.* "Pfft...are you serious? It doesn't need to be a genius to know that I'm the one 4 you"”
