Child Proof?

In the need to try to spin a positive out of this, I am going to say maybe my strong willed, entirely defiant two year old will grow up to be a very determined engineer. After he tackled his little sister yesterday for the 3rd time, Joe skipped the Time Out and went straight to his room with the "Child Proof" door handle "thingy." He hates that thing, as became very apparent a short time later. After a few minutes of loud banging and screaming coming from his room, there was silence. A few seconds later, I heard the door opening, and into my room walks a very proud little boy saying "HIIII!," with the biggest grin on his face. In all honesty, I was mad as heck, but I started laughing and asked him where the door lock was. He promptly walked into his room and pointed to the far corner of his bed, saying, "back there." So, not only did he thwart the "Child Proof"ness, he also went to the trouble to hide the thing from me. So, engineer? maybe, determined? yes! I would say that this is a good trait to have for life in general, so I am going to have to let it go that he is getting all of his practice on good ol' mom!
