I love how powerful the themes of friendship, togetherness and love are in those stories. Sam wise's speech at the end of two towers still gets me. Or when he tells frodo something along the lines " I may not be able to carry the ring, but I can carry you"
If youve ever had a meaningful friendship. You know exactly what is said/meant/implied/and unspoken when the auctioneer asks bilbo who a certain person was and he subtly replies "he.....he was my friend"
