I asked my wife last night why she thought I had changed more. Her response, of course, was with the appearance of Sophie. She said that Sophie is so much more talkative and out going. In the past she has said that Sophie is fearless. When she initially asked me, I wasn't even thinking about Sophie, and said it was her. Then I thought about Sophie and changed my mind. Then after thinking about it some more, I concluded it is still her.
