Kings Don't Share Castles

When you are in college it makes sense to share an apartment with someone because you two are on the same page and trying to get your life in order. I can even understand being in master's school and sharing an apartment too. 

But, after you get out in the real world any real man who claims to be "grown" should pay all his own bills and be the king of his own castle. If they don't they are not a real man. They are not a king.
