"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."
