'O' Man, What are we going to do with you?

Well, this morning our neighbor across the street called to inform us that our O-Man was out on our front sidewalk. Yes, he has learned how to unlock our front door and keeps going outside and hanging out on our front porch! We caught him out there three different times today, once with Sophie's boots on (which come up to his knees and he can barely walk in). Yesterday he was swinging a bread knife around in the air like a conductor. He is also climbing up on the stools in our kitchen and onto the kitchen island. The other day I walked into the kitchen and found him sitting on the stool calling someone on the phone. He is also climbing up on the top bunks of all the kids beds and throwing everything off. Little O, what are we going to do with you!???
