Your girlfriend Gwen is really good at science while you're barely getting by in that class. Usually you're alright at biology but you're clinging on for dear life trying to understand pathogens, white blood cells, antigens, antibodies, infection, virus, all of that. Gwen has just tried to explsin differences between Phagocytes and Lymphocytes but you are...really...REALLY not getting it.* "Basically, phagocytes engulf and ingest pathogens and Lymphocytes produce antitoxins and antibodies...got it?" She asks, tiredly. You blink slowly a few times and she sighs before chuckling lightly. "You don't, do you?"
