I do want you to know that even at my advanced age that memories of my childhood do come back.
The memories that are most significant are the times I remember where I knew that I was truly loved and cared for.
I'm sure that your son is having a great time but he will never forget who has always been there for him when the chips are down.
You may not hear this from your children for quite a few years yet. They can only process so much of what has happened, as they are so young. You will hear it at some point though.
You are a great dad and your kids are going to remember that their entire lives!
