Homecoming-week is very popular in the USA. It’s one week between September and October where the students wear clothes of different topics. So for example on Hillbilly-Day, all students look like a Hillbilly.
And on Friday, there is Homecoming, a football game. After that there is usually a big dance, but this year there wasn’t. So after the game we could meet each other and do something on our own.
At CTCS, there was Powder Puff on Monday, on Tuesday Hillbilly Day, on Wednesday Chapel Day, on Thursday Back to Future and on Friday before the football-game Black Out.
