HAha, I think that was in the Harry Potter books. I loved them!
I don't think he does. I know that I don't bother looking in their gardens, although, that's a like, I looked in once when cutting bits of a tree and I was up high and it is all concrete slabs and fake grass. Mibbe they are just entranced because mine looks like Narnia or something, lol!
I loved them too. To this day I am blown away by that universe too xD I guess I don't ever want to grow up even though I am told that I should act like grown up by now that I count as a grownup.
Maybe they admire your ability of keeping alive things alive :D All they have managed is making things look alive by using fake stuff. Though, I really dislike the fake look of fake things xD Why even try to replicate something to look like something it is not. Why not purple grass instead or a carpet?
It's a fabulous universe that one!
I am firmly against all those folk who tell others to act their age or grow up. I have had it name times myself but it's the secret of a good life to be young I think!
