What detail about his adventures with gollum did bilbo leave out when he told the dwarves the story? \?

The question is asking about what happened in the book, The Hobbit, of J.R.R. Tolkien What happened was that Bilbo did not tell the Dwarves about the One Ring the he found - which was the first time the Ring made Bilbo behave in a way as to protect it from others.

Ibelieve the answer is water and oil.
