Can we take a moment to appreciate John dressing up in a tie and whatever kind of blazer this is to go meet with Sherlock’s brother, waiting all patiently and trying not to take up too much space 

And he like stands up when Mycroft comes in, trying to be all polite and shit,

Just look at how impressive he’s trying to be.  Can you even believe this,, look at his tie and checked shirt and how professional he wants to look

and then like 3 episodes later he’s just like sup asshole, thought i’d have a seat, try and be more punctual next time, dick
