how i read genres textbooks vs. food menu vs. fairy tale

When reading a textbook i analyze the text more thoroughly and read all of the captions under pictures if i am studying.  I try to draw as much information as possible from the text as most of it is new information.  When looking over a food menu i may skip to breakfast, lunch or dinner depending on the time of day and what I am in the mood for.   I may already know what I am looking for or narrow the options down to a few select meals then debate between the two on which to choose. This usually does not take more that a minute and i choose my meal. However, when reading a fairy tale, i already know it is all fiction and i am usually reading for pure pleasure so I will usually read it at a normal pace. I wont analyze specific sentences like i would in a textbook or skip to certain parts like on a food menu.
