bonnie--to--your--clyde asked: Sherlock, how come you are so curious about John reading that particular book? John's right, you're usually not like that... Am I deducing something out of the ordinary here? Or am I just fabricating data to support my theorie? ;)

For one, he never reads those types of books; he usually goes for the classics. It’s an odd sight. And yes, I’m not curious, though I have my guessed for his intentions.

Is it wrong of me to want to read Harry Potter?

It’s a child’s book!

Yet you’re the one who thinks the planets revolve around the earth.

I never said that.

Right.. because I’ll believe that.

Must I restate the pact we made once more?

No, I can chant it in my sleep.

Superb, but what is the theorie mentioned in the ask? Something sexual, I presume.
