My mother would always buy a big turkey and all of the usual foods that go with it. Just wouldn't call it "Thanksgiving". She said that there is nothing wrong with turkey, and turkeys are more plentiful at this time of year.
When I left WT Land, I noticed in my reading that many other JW's shared her sentiment.
Okay, there's nothing wrong with pine trees. I just happen to like the smell of a pine tree in my living room. I enjoy decorating it all up. It's just that these trees are more plentiful at this time of year. I just won't call it "Christmas". Nothing wrong with that, right?
