My Dad's 70th bday....

Today we celebrate his 70th with a surprise party at a restaurant with family and friends. Not sure what I am thinking. Will my kids do this for me? Technically I am doing nothing as Mom is throwing this shin dig but you get the idea. If I am alive at 70 I'm sure there will be a party. Silly thought but you always wonder will there be a point where they will reject you. You know the kids will think of you always as dad but that thought is always there especially when a toddler is a toddler and is just talking back as they always do.
