1 I would say 'tree'. But if you take it in the metaphorical Tolkien sense, I'm definitely more a leaf (i.e. I get so fascinated by details I often don't finish the big picture).

2 Father Christmas. Random fact: in parts of Brandenburg, they used to say Easter Eggs were brought by a fox.

3. Jane Austen. Mind you, it's worth having Jane Eyre for The Eyre Affair and follow ups alone!
