Miller was aware that needing to have things explained to him could easily have become an avenue for embarrassment. But Ray didn't open that door, didn't even crack it. He seemed to greet their cultural differences like they were marvelous and not inconvenient at all.
He made a mental note about soggy microwaved buns, in case he ever got bold enough to try and replicate the meatball sub thing for Ray. "It's a date. My fridge empties out pretty quick, so there's certainly room. That reminds me, I've got some chocolate left over from Christmas you should help me with. I hear it goes bad if you keep it for too long. Maybe you swing by again tonight? We can talk more about throat spiders. I feel like I've got a lot more to learn."
As innuendos went, it wasn't the most obvious or the most sexually charged. But Ray would know what he was referring to. Hopefully.
