I have had a situation, that has needed some imagination. You see I have two boys who want to go outside whenever they feel like it. They have even gone to the extent of going into the garage, opening a car door and clicking the garage clicker to get outside and play. I now lock my car doors. My one problem was the sliding glass door. Without actually driling into the metal for a special lock, I have tried to keep the kids out. But they would open it whenever they wanted and head down the road with me running after them. They actually usually just want to play in the front or the side and I tell them they have to wait until I can be out watching them. Then they take off on their own. Anyhow, the other day I was just so fed up and thought that I needed to figure out SOMETHING!! And I did!~ I took a pole that usually has a duster attached, but it unscrews, so I wedged up high into a small space at the top of the door and VIOLA! I was sooooo excited about this discovery. And the kids are very sad, but seriosly, I couldn't even shower without locking them in the room with me to guarantee they wouldn't escape!
