leave a brotp/platonic ship in my ask and i’ll tell you:

• who steals french fries off the other’s plate: chester lewis. and it pisses off sherlock so much, although he doesn’t ear all that much.
• who jokingly moves in for the kiss when someone asks if they’re a couple: neither. they is no romantic or sexual attraction between the two. they’re mere acquaintances, friends at best.
• who has to bust or bail the other out of jail: sherlock. he has friends in all places, especially in scotland yard, so when chester’s curiosity gets the better or him, sherlock is there to help. occasionally.
• who gives the other advice/comfort about dating issues: neither. sherlock doesn’t date, it doesn’t interest him, so any advice for chester, the one who is open to the idea of dating, would be false.
• who shamelessly cheats at games by reaching over to cover the other’s eyes: chester. actually, both. two highly intellectual men who have a very competitive, borderline narcissistic tendencies & personality, playing a game? oh, you can bet there’s going to be some cheating going on.
  
• who immediately calls dibs on the top bunk: chester. sherlock doesn’t particularly sleep all that well, & whilst chester is nocturnal, he does need time to sleep in the morning, so top bunk it is!!
• who starts and who wins the pillow fights: chester instigates nearly all of them, but he can’t win one to save his life. sherlock almost always beats him.
  
• who says “your pants would look better on their floor” to the other’s potential crush: sherlock!! common courtesy, especially in romantic & sexual situations, doesn’t exist.
