"Memories hide. We file them away." She took a deep smell of the warm popcorn and popped a couple pieces in her mouth. "I remember my brother, and sitting by the hearth and popping corn in the fire but not until I smell popcorn. Until then it's there, the memory is in me but I don't know I know it."

That was very coherent of her Peter, be proud.
