Cutout copy
When you can not make it for the holidays, maybe the only option you have left is to do what this guy did, send your family a cutout copy of yourself. You may not be able to speak or do really anything at all, but at least you will be there in spirit.
They can still take a group photo with you and make some memories, but for the most part, you will just be a lifeless piece of cardboard. If a video call is not working, we think that this could just be the best possible option. Do not try this out though if you don’t have to, grandma would still prefer to see you in person.
