What it is that's wrong about doing this sort of work, John wouldn't understand if someone were to sneer at Sherlock for it. It seems stupid and more something out of a grudge or just because, rather than there actually being anything wrong with it. Because there isn't.

Which he's certain Sherlock knows too.

The idea of people running around shouting things in English to do magic, though... The image of it makes him laugh.

"Incredibly daft."
