J is a lot like Karl, only opposite!  You guys get it right?  Well, maybe Karl could have found a clearer way to say that he and J have a lot in common but are still different people.  I know it's difficult to take all those sayings or slang phrases in English away and get used to speaking straight forward but Karl needs to get used to it.  If things work out for Karl and Mai, I'm sure she'll learn plenty of his strange English sayings.
