Das mine!

Arthur's new favorite phrase is "das mine" and he says it all the time even when whatever he wants is clearly not his. 

Occasionally he says it to me in an angry tone and I tell him that he can't speak to me like that. Last night when I told him for the hundredth time to stop jumping on the sofa he looked me square in the face, pointed his fat finger and said " don't talk to me like that" before taking one more giant bounce on the sofa.  That was his last bounce of the evening.
