Locked Out

My wife was outside tonight and I followed my daughter out as I was carrying out a bag of trash. I proceeded to shut the door behind me before realizing my son was wanting to come out also. I called out to my daughter asking her to open the door. She told me it was locked. Great, we were locked out and my 2 year old was inside. I peaked in the window next to the door motioning to him to unlock the door. I could hear him moving the deadbolt. I'm sure he was locking the door even more. He remained calm and finally opened unlocked the door. I knew he could because he has unlocked and opened the door before and let himself outside without us knowing. He's a pretty smart guy. Takes after his mommy.
