Family emergencies took us to Palo Alto. Bruce and Carla were welcoming and understanding. One afternoon we brought our granddaughter to the apartment. Carla brought bright stacking puzzles for her to play with. Our hours were erratic but the light was always on outside for us. On the hectic morning that we were to leave, I forgot medicine in the bathroom. Carla went out of her way to track us down and catch us just before we left our son's apartment for the airport.
