Rewards in parenting

This weekend, my daughters and I worked on a new super-crazy fast snow sled (built up on old cross country skis) and an ice boat (sail, mast, seats, and runners). Sylvia was working with me and asked "how did you learn to build stuff?" I answered, truthfully, "by working with, and watching, my dad." She smiled broadly. Mara reports that with the sled and boat that "this is going to be the best winter ever." I melt.
