Do you know what I love the most about this?
Sherlock has said that he only saves important data in his hard drive, in his mind palace.
He is very worried for everything to be perfect for his best friendâs wedding. And also heâs afraid that things are going to be very different now that Johnâs getting married.
He is very detailed with the little things, like the piano starting exactly at 11:43.
So he doesnât just only learned those tricks with the napkins, but carefully saved it in his mind palace.
This is not an important information or something he is personally interested of, this is for John. So itâs important to him now because itâs for John.
Somewhere in his mind palace, thereâs an special spot for folding napkins that was âbuiltâ specially for John. Like a pedestal in Johnâs admiration room for something he would never have considered important otherwise.
And that image gives me life every time.
