Why am I not named after Daddy?

  As James was eating his breakfast this morning, he looked at me with sad eyes and said,
  James: Mom, Sam's middle name is Paul, Daddy's name is Paul and Grandpa's name is Paul.   But my middle name is just Michael.  Why am I not named after Daddy?
  Me:  Well, son, Sam was born before you so he got Daddy's name.  We didn't want to give you the same name, so we gave you a different special name.  Michael is my dad, your Grandpa's name.  It is also the name of several relatives that have died already.  You got a very special name too!
  His eyes lit up and he said, "really?"  He smiled on went on with his breakfast.
  It was neat to see this 7 year old think about things like names and where they come from.
