Hey Mark,
We're sending prayers your way. It's part of human nature that as they get older, the youngsters don't need dad as much anymore. It doesn't mean they don't love you any less. It just means they are growing up. I'm going through that everyday but I wouldn't have it any other way. Hang in there. One of these days there will be another youngster coming along who will be calling you "grandpa". When that happens, you'll have your hands full all over again teaching him or her the fine points of traditional archery. Keep the ol' chin up!
