It is where Strong Sad sleeps, plays board games with board games and waits to be pummeled every hour on the hour. He has a poster on his wall that reads "Boys Don't Cry".
Actually, it's of a band called The Cure and i'm guessing they had a song called Boys Don't Cry. Also, he has a poster for the movie Some Kind Of Wonderful. -Ace101
He also has a purple poster of the Promise Ring right over his bed.
