      Send ♡ for a friendship headcanon

      Sherlock has never been the best at making friends. He doesn’t,
      however, alienate himself.    He knows, at a glance, who is worth
      his time & who isn’t.     In his younger years, this meant knowing
      who might befriend him only for the sake of cruel intentions later
      (think Carrie); in his older years,  it’s for knowing who might want
      to be close to him for his social status (you. repel. me.)

     Sherlock, on the other hand, isn’t one to judge based on one’s 
     own social status (his willingness to work with the homeless; his
     friendship with a  recently  retired  Army  fellow who was looking
     for a cheap place to live with a less than best family history). To
     further headcanon,      I would say that Mr. & Mrs. Holmes were 
     the type of folk that would take in one of the boy’s schoolmates
     for Christmas   dinner if they didn’t have a place to go otherwise.
     (This is not to say the  Holmes   household was warm come the
     holiday season;   but, Mr. Holmes seems like a personable man,
     and Mrs. Holmes seems like the type to have a sweater made
     with your initials on it.)

     Moreover,   for those who are on Sherlock’s good list: he is very
     loyal to those he considers friend.  He certainly does not always
     express this in the most conventional way       (I’m calling out him
     for drugging John right now),   but he has those whom he loves,
     and he would do what it takes to protect them      (see: TRF, the
     Americans vs. Mrs. Hudson vs. Mrs. Hudson’s flower garden.)

     TL;DR:      He’s not a perfect friend,     but he does consider himself
     to have them, he’s loyal to them (in my mind), is open to a friendship
     with anyone genuine, and is a (unintential?)jerk once befriended.
