Ok today is Smart Gilr's birthday. She is answering the phone because all of the calls are for her and she is so excited. The Cousin and the Saint have a surprise for her birthday and she is dying from the excitement. She told The Man that she has clues that she has to solve with her dad and then she will know what the surpise is and the living room (?) has presents!
The Man doesn't think she knew it was him considering that she was actually talking to him because she doesn't like him for some reason. But the excitement of the surpise outweighed her usual caution so she talked:-)
