Where are the Door and the Window?

A few weeks ago Dana and I were cleaning up the floor of the house (we have cleaned the floor a number of times since then and clean it more often than every few weeks). In the process Dana could not find the spool of thread that had fallen on the floor earlier in the morning. I also was also not able to find the door and window to Ilan's Baby Einstein Puzzle Book, which he received as a gift from Batya Levi, and the elephant to his safari tractor. After vacuuming and cleaning the floor we were still unable to locate any of these items. The next day Dana found the spool of thread in its proper place, in the drawer. She asked me if I put it there, which I had not. Dana did not think that she had put it back and wondered if Ilan had possibly put it there. Later that day, after Ilan had awoken from his nap, I asked him if he knew where the door and the window from his puzzle book were. Without skipping a beat, he walked over to the sewing table, which also doubles as a television stand, lifted up the cloth covering the table and opened one of the top drawers. I looked down and there inside were the door and window to his puzzle book. I was shocked that he intentionally placed them in the drawer and that he remembered where he placed them over a day later. It also solved the mystery of how the thread was in the right drawer. Incidentally, we still have not been able to find Ilan's elephant.
