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

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