Yes, I know it's Thanksgiving break and you are spending the next three days at home stuffing your face and getting tipsy behind your parents' backs, so won't have time to focus on your research paper.
No: telling me that you "need" to shop for Black Friday deals by staying up all night to hold your place in line and, therefore, won't have time to research your paper doesn't merit an extension.
No: I cannot do the research FOR you and send you links to the articles I've found because that will make your paper so much easier to write.
No: I cannot scan three pages and email them to you out of a library book that you didn't check out and now realize you need for your final paper.
Yes: I will assign an F if you don't turn the paper in on time.
Are you going to next ask me to write your paper FOR you?
