You only knew Sam as, your best friend, Carly's boyfriend. You never had a problem with him. Even when Carly complained about him being too touchy or obsessed. So when she told you she broke up with him you shrugged.

After you finish your lunch you excuse yourself to the bathroom. After using it you walk out of the bathroom to find Sam squatting down beside the vending machine. Trying to hide the fact he was crying. Feeling conflicted you decide to walk up to him.
