Our daughter's all grown up and a mother herself now. But she still remembers the day she got lost at the grocery store - and all the feelings that went with it. She was four - her baby brother was in the grocery cart - she was walking ahead of us as we browsed the aisles for our next meals. Somehow, she got way out ahead of us and into another aisle. She kept walking until suddenly she realized that her parents were nowhere around. She remembers it as one of the traumatic moments of her young life - she said, "The aisle was so long, the shelves were so high, and I felt so alone."
