It's breaktime and you both don't know what to do, so you turn to him. "Okay, I'm going to come up with a number in my head, you try to guess it."

He smiles at you like he's deeply in love and nods slightly.

You think about it and come up with the number four. He looks at you and wothout hesitating a second he says: "Four."
