Last Thursday was my 2nd DD 's birthday . She had requested an angel food cake for her birthday cake . I got home from work , mixed it up and tried to preheat the oven . Five minutes later , I was wondering why the oven was still not up to temperature .

Question: Why is the narrator spending so much time baking ?
Answer: It is for work .It is for a friend .It is for a class .It is for personal consumption .
