The story might center around the relationship between a baby reindeer and a human. In some areas, reindeer are domesticated to some extent. So, it could be about a person who takes care of a baby reindeer and the bond that develops between them.
Well, I'm not sure exactly which true story it is based on. But generally, a baby reindeer might be born in the wild, perhaps in a cold and snowy environment like the Arctic tundra. It would stay close to its mother for warmth and milk. Maybe it faced challenges like predators or harsh weather while growing up.
In the story, there might be a situation where the baby reindeer gets injured, maybe by stepping on a sharp rock. The herd might slow down a bit to let the mother take care of it. Or it could be that the baby reindeer discovers a new grazing area with the herd. It's excited to explore this new place with lots of fresh lichens and grass, which is an important part of its growth and development.
