What's in a name?

The word ”daddy” has been used in my vocabulary my entire life. When my daddy passed away I still called Dennis daddy because we had kids in the home.  Slowly, as the kids get older and have kids of their own, I have realized there isn’t the need for that word in my live like there once was, and that makes me sad.  I miss having a daddy in this world.  I miss having little kids in my home and I miss the simplicity of the family unit when both were in use often.
