run away
You turn around and run about a hundred yards. "There, that
shoud be far enough. After all, trees don't have legs, it's not like
it can chase me down." Then you start to think, "Wait a
minute, trees also don't talk or have dogs attached to them or carry
chaisaws." Sure enough, you look back at the tree and it has
uprooted itself and is running after you with a chainsaw like a
madman.... er... tree.
