I don't think this ad is one of their best and didn't watch This Morning annemac but I thought, just my opinion, it was made quite clear he was the man in the moon rather than a grandparent. And at the end the message on the bottom of the screen is reach out to someone at Christmas. Where it seems to have come unstuck is where GC have been told by their parents their much missed Grandad or Grandma is now on a star, on the moon.
I think they also played it safe with the little girl befriending the man on the moon because of the near hysteria at times, sadly. An elderly person sitting on a park bench near a children's playground being asked to move was one story I'd read recently, admittedly it was I think in the Daily Mail who love to sensationalise, but smiling at a child on a bus, a train, completely innocent behaviour can be unwelcome nowadays.
