If I had been a better parent we would have talked about the meteor shower. I wouldn't have just bought a telescope for Christmas without learning with him how to use it. I would have spent more time watching the stars with him. I would have learned to fly planes with him. I would have read all the Harry Potter books while he read them. I would have asked him to cook with me. Plan a meal, search for the ingredients.
I would have spent more time being a parent and less being whatever else I thought I was.
