When Legolas asks what gift Galadriel gave, Gimli tells him about the three golden hairs.
There are other things, more cherished and more secret, that Gimli does not mention.
He does not tell Legolas how the Lady led him away from the others, the night before they left.
He does not say that she told him she would leave those shores, when the Quest was done.
Especially, he does not speak of her desire to know that the Elves would be remembered with warmth by one Dwarf, at least.
And he never mentions her other gift: a single, gentle kiss.
