It's been a long time since I last spoke to you, and we both know that today is a special day. I'm not sure if you know where I am, or what's happening in my life, but I like to hope that you do and that one day you'll be able to talk to me again. I know that if you do, I'll have a lot of catching up to do, and that's something I really would like us to do together.
I realise you may not know this, but every day I wonder what you're up to, and really hope that you're happy. Every year on this day, I wish most of all that I could be there with you, helping to make your day special. I hope that you're having a fantastic birthday, and that it brings you all the things that you'd like.
Happy Birthday son,
With all my love,
