"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]
