The 'a grand old tree story' could be about a very old tree in the forest. This tree might be home to many animals like birds and squirrels. It has stood there for a long time, through different seasons and weather changes. It could have a magical quality in the story, like being able to talk to those who are kind - hearted and listen to their secrets.
I'm not sure specifically as I haven't read it. But generally, it could be about the life of an old tree, perhaps its experiences over the years, the animals that live in it or around it, and its significance in the local environment.
In 'A Christmas Story', 'ch distillery' could hold great significance. It may be a place that has been around for generations and is deeply intertwined with the local Christmas culture. It could be a place where secrets are shared, relationships are formed or mended during the Christmas season. For instance, a character might work at the distillery and through their experiences there during Christmas, learn important lessons about family, friendship, or the true meaning of the holiday. It could also be a place that attracts visitors from outside the town during Christmas, thus contributing to the overall festive atmosphere and the local economy.
