A happy memory popped into my head last night...playing "turtle" with my brother. We were at a hotel pool...I don't remember how little we were, my brother was may 5-7. He would climb on my back with his arms around my neck and I swam to the bottom of the pool or loop around the pool and back to the surface. I remember being so careful about making sure I didn't keep him underwater for too long, but I remember how happy he was, his little laugh and he'd tell me to do it again. That was a very happy memory.
