You are Gramp's assistant and he is currently driving the train, looking focused as he keeps talking to himself. His talking can be annoying so you have to endure it. Also, Gramps doesn't like it when you try to ingore him. He likes attention, and doesn't care who it's from. Anyway, you see Gramps get flustered and he blushes, as he is about to fart.

"Ohh no... Not another one..."
