Hm, I used to fake sicknesses, but a few times I'd hide out or walk the halls and just not show up to class because I didn't want to take a playing test in orchestra or something. But I've also just called the office pretending to be my mother telling them I'm sick and not showing up today, because if they didn't, they'd call our house 50 million times letting my parents know I didn't show up. They even did that if I was late to class by 5 minutes, so annoying.
