Four years ago I started smiling, and it has not stopped. I have enjoyed every stage of your life- from the first time I held your hand to watching you first read gate signs at the airport yesterday.
Most dads think their children are smart - but there are two parts of you that I really love:
You get a look in your eye when you are going to tease someone, and love to do that and you are very kind. At play areas I see you helping smaller children, with care and gentleness. You have this genuine smile, and joy in your life.
So as you grow and at times life will toss things and you may feel badly, look back into that part of you - smile, be kind, joke with those you love and know that your life made this dad the happiest his life has ever been.
