How true is your observation. Once gone, it is too late to say all the things you feel. The last time I saw my dad, I don't remember if I told him I loved him. That has bothered me a lot since.
Since then, I have made absolute sure to tell my kids and grandkids I love them. Also, I lost my mother in August. I knew she was failing, and you can be sure I told her I loved her. She said, "I love you, too. You are a good son." What sweeter thing could a son ever hear? Mom died the next day. Let us all make sure that we regularly remind our loved one how dear they are. But especially at Christmas time, let us reflect on the blessings we enjoy all through the year, and thank God for these wonderful times.
Amberjack, I understand exactly how important that final good-bye was for you. I'm glad you were able to let him know how you felt. God bless.
