That's my James. Nobody ever asked James to put his dirty dishes on the counter. He just started doing it one day. This is the power of learning from your older brother. It was really a struggle to get Nathan to learn to clear his dishes from the table (still is at times), but James rarely forgets. He's learning not to spill.
James is like this for pretty much everything...he doesn't ask you if he can do things, he informs you that he's going to do them (if you're lucky). If he gets it in his mind to do something he just makes it happen. If you get in his way, you're going to hear about it.
