How scary! That's exactly why I wanted a 2nd or 3rd story apartment when we went looking for a new one -- I know that Jack would be through a ground level screen in no time. The ground level apartment was gorgeous the way you could just walk out onto the lush green lawn...but all I could see in my mind was Jack jumping at the screen ONCE and scooting right through. I know if we are on the 2nd or 3rd floor they will just look out, like they do now. Your story made me feel like putting chicken wire up around all windows! 8O
