Ohhh... tears here, too. I'm lucky enough to live near my grandchildren and see them at Christmas and so forth, but I know not everybody is (sigh).
Don't have time to read all the responses, right now. Will come back later. Hope I don't just repeat what someone else has said.
However, I'm not surprised at the advertising - kind of expect it around this time of year. Anyway, I think they're just trying to say that, even if someone is far away, you can keep in touch with them and they with you through gifts and so forth. However, it leaves a lot unsaid. As one poster mentioned, for example, why didn't they invite the old man (grandpa, maybe?) to come for Christmas, instead of just sending him a present? Perhaps they did, though, but it's too hard for him to travel. We don't really know.
Also, I see the use of another planet as trying to show how some people feel when they're far away - as if they're on another planet from their loved ones. However, I can also see where this might just upset some long distance GPs, rather than make them feel understood or encouraged.
It also makes me think about all the GPs who won't get a present from their loved ones, this year, or who send a gift and don't get a response. Or who are, unfortunately, estranged from their GC's families and don't know if their gifts will even be accepted or have them returned unopened. Hopefully, there aren't too many of those, but I know they exist. This advert could just make them sadder. However, they probably weren't thinking about that when they made it.
