You had joined the Company of Thorin Oakenshield to help them reclaim Erebor. A friend of Gandalf and a new friend to the dwarves, the only problem was that you are an elf. Because of that, Fili didn’t like you very much and often teased you during fights or riding the horses. As you rode out of the shire on your horse Fili rode closer to you and spoke up

“You look ridiculous, like you are about to fall off your horse!”

He snickered looking at you with a grin on his face.
