Oh man, haha I would say don't even worry about work week until you're in a sorority, lol. I may be the only one, but I think work week is my least favorite time of year. We try to make it as fun as possible, but really when it comes down to it, practicing singing and screaming/chanting and bouncing outside in 100 degree Missouri August heat...well, yea it's not pleasant.
But basically it is just a week of prepping and getting pumped up for rush and going over last minute details. Dress checks, conversation workshops, decorations for everyday, and a bunch more stuff. We usually go from 9 am to 9-9:30 pm everday during work week so it gets long. Just make sure you get enough sleep, which is what I should be doing now!
