Two things I want to remember forever:
1) Sitting with my Dad late on a Christmas eve at my grandma's house, totally exhausted, and listening to the sound of his voice and his heart beat through his chest. That's the best way to hear a dad's voice.
2) The sound of my Mom's high heels (though they were called PUMPS back then) click clacking on the entry way floor of our house, the hustle & bustle and smell of her perfume. It meant they were dressed up & going somewhere fancy.
