Rowen came over and visited for the day.
We found several flashlights and but couldn't really appreciate how bright they were until we tuned off all the lights in the room. Once the lights were turned off it was, of course very dark if you didn't count the noon light that was coming in the four large windows. With the main lights off, it was impossible for me to see him because, you know, the lights were off. He would turn the flashlights on and then I could see him again. This game of virtual hide and seek went on for about 20 minutes.
We also learned that if you don't hang onto the railing on the stairs you can slide and bump your shins. He only had to do that once and he became the railing police. One hand on the railing was good but two hands was better.
