All right so eventually some of the purebloods have to make friends with the Muggleborns, despite the fact that they don't even understand half of what the Muggleborns are saying, and over the summer they get invited to spend a week at the Muggleborn's house.
Take a moment and imagine a pureblood who has relied soley on magic up until then in a muggle world with no magic at all and nothing they understand.
It's like someone from the 1800s being brought back all right
