We’re thinking about staying here and inviting friends over in the afternoon and having the evening to ourselves.

I expect I must be on my best behavior?

Yes. 

And that I must clean my mess up beforehand?

Yes.

And that I have to buy you a gift?

…Fine? That easily?

Sure.

Sherlock, that’d… that’d be wonderful. Thank you.

Merry Christmas, John.
