Complicated situation

Re: Complicated situation

She was nodding to what I was saying like I opened the conversation with statement that she eats quite late to which she just nodded.Then I said that we had a meeting in cafeteria few hours ago.She just stared blankly at my face. She was not very interactive like giving her input etc which just increased my doubt about her interest.
I notice very subtle things like the way she was sitting facing me like she wanted me to interact with her which is unusual.She always sits facing television in the cafeteria but this time she changed her sitting position and was facing me.I don’t know.
