David, I am so glad you had this weekend with the cub scouts and shared it with us. It is a great testimony that we all need, survivors and caregivers, some "normal" time in our lives to enjoy living and not thinking all the time about the lung cancer. And it is perfectly normal to cry at the thought that those times are limited for you. But, as people have said here, you don't know when that will be. You can well get to see your children grow up. See the people here that have many years after the diagnosis. I agree that you should let your wife know how you feel, and let her tell you how she feels. This is a time to draw closer together. Don't pass up any chance to grab onto some "normal good living" as it comes by. Blessings. Don
