My favorite stuff by Tolkien are his children's stories. I love Roverandom, The Father Christmas Letters, and stuff like Leaf by Niggle and Father Giles of Ham. It is a shame the man wasn't a published children's author during his day, I feel like he really excelled at it, but of course, it wasn't really his thing and just fun stories he wrote for his own children. I am sure he would have much rather been well known for his academic works and for his Middle Earth stories.

I've never read any of this, in fact I haven't even heard of it except for Father Giles of Ham. More for my reading list!
