"But the Forest is queer. Everything in it is very much more alive, more aware of what is going on, so to speak, than things are in the Shire. And the trees do not like strangers. They watch you. They are usually content merely to watch you, as long as daylight lasts, and don't do much. Occasionally the most unfriendly ones may drop a branch, or stick a root out, or grasp at you with a long trailer. But at night things can be most alarming, or so I am told."
