C# simple simulation

I'm trying to make a simple simulation program in C# which takes enviornmental variables and changes the moods of the student and teacher depending on temperature, time of day, day of week. I've set up a class for parent class: PERSON, children classes: STUDENT, TEACHER. There is also a CLOCK class if one needs to be built. You will also be provided with some additional xml files to manipulate if needed, but the student information can just as well be stored in the individual classes. Once the START button is pressed, the emojicon pictures will change in mood according to variables and if PAUSED button is pressed, the student details will be displayed. There should be a clock or a counter in seconds to count how long the program runs before it ends after about 150 cycles.I would like for you to build on the file I've created. My understanding is that this is something simple and should take less than 2 hours to complete, however if more time is needed, please let me know, but no later than Sunday 12/11/2011.
