Thank your son for his service.
It is hard to see them go but it is great when you realize they can be independent. All 4 of mine are so much their own person. They don't need me to get along on their own and they actually go to each other with their problems more than to hubby and I which I think is good. Law of averages is that we will die before they will and then they will have each other. We do see all of them on a regular basis and have a good time together. They have all thanked us for being great parents. What more could you want?
