You'll step up to take care of business on monday even though you'd rather forget it and go party. Someone needs you and that's that. Midweek is a great time to look at coworkers or fellow students in a new light and see if there's some hidden hotness lying in wait. If you keep an open mind about people through the weekend, you'll learn something new that will knock you out. By sunday, you might be the last person left in your group with any energy to have fun.
