Rosanne is not sure how she feels about Bob... or Robert Smith. She is obviously not happy about the fact that he can be a little harsh towards her. Granted, there were also a few moments where he was very tender. Especially the way he looked at her.
But Rosanne is still annoyed by her confused feelings.
"Whatever, stupid Robert Smith. A.K.A. Stupid Bob! I have a crush on someone else already!"
Rosanne finds herself walking to a World War II History Museum not too far from her apartment and Times Square. That's actually the reason why she wanted to live in this busy, hustle and bustle tourist area. She loves that museum. She finds comfort in that museum.
And there is another very important reason. She can see her crush in that museum. Unrealistic crush, though.
