I don't see it as a lie. More like, encouraging imagination. They are kids, they find love in something that isn't real. They can. Imagine wonderful things in the world. There doesn't have to be logic to everything. Its the beauty of seeing kids enjoy something. To believe that some part of the world can be good
Adults over anylize everything. Everything has to have a reason, and so on. I say no. The kids enjoy it. It doesn't cause any harm. Its believing in something greater. Just like those who believe in Jesus and god. Believing I. Something we can't see, doesnt have to make sense. Stop anylizing everything about the world.
Just know that children enjoy it. You once enjoyed it. Let traditions be happy, stop trying to find a reason.
