Imagine that at the end of Dumbledore’s speech at the beginning of the year, he asks if there are any questions, and one first year muggleborn kid raises his hand, whips out a smart phone and asks for the wifi password.
And then Dumbledore just casually says “Sherbet lemon, with a capital S”, and commences the feast like it’s no big deal while the non-muggleborns think WIFI is some sort of secret society.
