You and Graves are sitting next to each other, just chilling and not talking. He's chewing noisily on some gum then he takes it out of his mouth and attempts to throw it in the trash without getting up.

He misses. Badly. It lands in your hair. He realises he has fucked up. He quickly and suspiciously scoots away from you before getting up and leaving you, walking away, hoping you don't realise he got gum stuck in your hair.
