Bad day

Sam knocked on Dean's door.
"If you want to enter you have to tell me the password, Sammy."
Sam just raised his eyebrows.
"A password? What are you, Dean? Ten?"
"So it's only you, who can be childish?"
"What are you talking about? Can we just talk like two adults? Please, Dean!"
"Now you want to talk? Now!? Maybe you could try it months ago? Before you started to sneak out of bunker every night... you thought I'm not gonna find out, that you are fucking that pipsqueak?"
Sam is watching the door in horror, this is really not good.
