Galadriel vs Feanor in the U.T.

I don't know if this has already been mentioned somewhere but perhaps she gave Gimli three strands of her hair because she refused to give Feanor a strand of hair three times, so this is like a last 'sucks to you" at Feanor. He asks three times she refuses, many thousands of years later Gimli asks one and she gives him three sort of as a 'rememberance' of her uncle.
