Excuses

This is how my morning went with Isaac:

Me: Isaac, I need to change your diaper.
Isaac: I can't.
Me: Why not?
Isaac: I too busy.
---------
Me: Isaac, can you go and get me the clothes that are laying on the floor in your room?
Isaac: I can't.
Me: Why not?
Isaac: I pooping.
--------
Me: Isaac, did you poop?
Isaac: Yah.
Me: Well then I need to change you again.
Isaac: I can't.
Me: Why not?
Isaac: I paying. (playing)
---------
Me: Isaac, it's time to eat breakfast.
Isaac: I can't.
Me: Why can't you eat?
Isaac: A-cause. Don't want to.
