My oldest son (22) has never really been into my Christmas lights or BBQ hobbies, but my youngest (17) has always been involved. He has been a big help over the years, especially since he hit the 6' tall mark (now 6' 3"). I will sure miss his help for the next four years while he is away at college. I will have to redo my 16 foot tall "mega-tree" since I currently raise it Iwo Jima style with the help of my son and one of his friends. I guess I better start working out and get in better shape.
As far as being a fan of the light show, I don't think he really believes the show is worth all the work. My biggest fans are the elderly ladies of the town.
