Homecoming week

I think homecoming week is silly. Why would you dress up every day differently every day of the week. It's pointless to dress up all its for is a football game and a dance. My question is Why does it  exist, and who thought of the idea. It is the worst Idea ever. Most people don't dress up for it, and it distracts kids from school and work time in class. The only good part about homecoming week is friday you get out of school early because of a pep rally. That is why I think Homecoming week is pointless.
