I tried to ask her where she went. She just looked at me and wouldn't answer. I never knew her very well, but she isn't herself. I don't know what happened.

Right before she left, she seemed nervous. When she came back, I was relieved, but seeing her now I feel more confused than ever.

Every time I talk to her she won't answer. And she just stares into space for long periods of time. Last night I couldn't sleep. I know it sounds crazy, but it felt like she was looking at me. I heard her leave in the middle of the night...I don't know where she went.
