Twice in my career I've taken leave and found it difficult to return. The first time, when my son was born. The second, this past week. I was on Cape Cod for our annual holiday and felt really, truly present for my family in a way that I don't feel often enough. It also happened in Brazil when we went for the World Cup, so this has been a summer of reflection about what kind of dad I want to be and what kind of relationship I want my family to have with me.
