"Go not to the Elves for counsel,
 for they will say both no and yes.
 Elves seldom give unguarded advice,
 for advice is a dangerous gift,
 even from the wise to the wise,
 and all courses may run ill."

 "But what would you?"

 "You have not told me all concerning yourself;
 and how then shall I choose better than you?"

 [Gildor says this in response to Frodo]
