Came across this in LOTR, felt relevant

"It was not the fault of the Dwarves that the friendship waned," said Gimli.

"I have not heard that it was the fault of the Elves," said Legolas.

"I have heard both," said Gandalf.

— The Fellowship of the Ring by J.R.R. Tolkien

I was rereading LOTR and came across these lines. Maybe understanding starts when we accept that both sides have their own stories.
