this is the email i sent my teacher just now

Hey I am in your Abnormal Psych class that meets Tues and Thurs 12-30 to 1:45.

I just wanted to let you know that I am uncomfortable doing the assignment to go to Wal Mart. I used to work there and I don't want to embarrass myself in front of my former co-workers and managers. Also I think this assignment has nothing to do with the class we have been taking. And I also find it inappropriate and see it as making fun of other people. I would appreciate if you would not count me absent on that day and not give me a 0 for the assignment. I hope that you can understand where I am coming from. Maybe there is something else I could do for the grade. I would be willing to do another assignment instead of getting a 0. Please reply back to me before Thursday. I'm sorry for the inconvenience.
