Robert pulled Odette to the side of the lake and sat down on a stone bench beside her. He looked at her and said with a smile, "Since Miss Odette doesn't want to say it herself, then let's guess. Seeing Miss Odette so sad and come out by herself life this, I think she must have encountered some emotional difficulties."
It was really easy for a smart person like Robert to guess what would have happened. Since Odette was crying beside a lake with no one around at this time of the day, it must have something related to Eric.
But he could not ask directly. Hearing what he said, Odette remained silent. So she tacitly agreed. "Since it is a matter of feeling, then there must be a third person among you." Robert made another guess.
