Question pretext
    
                                    Now I would like to ask you questions about what you did yesterday.  I want you to try to remember the sequence of activities that you did from when you woke up until when you went to sleep last night. 
I will start by asking you what you did in the morning yesterday, and you should just give me a short description. Then I will ask about the afternoon and then the evening.
