Door handle

A can now open the bathroom door.

We have the lever handles (like this), and he can do it now.

He only seems interested in opening the door to get OUT of the bathroom, but I guess that's because we no longer have the privacy of leaving the door to the bathroom closed... that's right, if he hears the word "bathroom," A knows where to go, and that it's his right, his duty, to follow us in.
