After the post-lunch meeting, all the children were gathered in the dining area and were engaged in a spy game that Bobby had devised himself! It was very intricate, well thought-through, and apparently something he had been working on for a while, as I learned afterwards. It was a great success!! Nevertheless, despite the excitement, Bobby still wanted to work on Solar System stuff (he drew a model on his door in invisible ink) and browsed through Astronomy Picture of the Day.
