Well, since I have a cold and didn't want to share my germs with anyone, I stayed home from Bible study this morning. Dh took ds to his Bible study and I picked him up. When he got to the car, he handed me a piece of paper with a drawing on it and asked if I knew what it was. I looked and immediately saw a submarine. I looked again, and Lo! it is a drawing of the Hunley! Several months ago we watched a show about the Hunley on the Discovery channel, and did about an hour's further research online afterwards. He remembered all that detail since then! Wow. I am so impressed.
