Here is how you can ditch school and fake your parents out the Ferris Bueller way. While your parents are at work, you can have a whole day of fun with your best friend and girlfriend in the great city of Chicago... I mean whichever city you're from.
Act like you are not feeling too well and have no energy inside you to get up. Maybe a little lifeless eye blinking will help convince your parents that you're really sick.
At this point your parents may touch your forehead to see if you have a fever, but of course you don't. The clammy hands approach is the best way to make them think otherwise-- it's physical evidence of illness and as Ferris would say "It's a good, non-specific symptom." Fake a stomach cramp and when you're doubled over, moaning and wailing, lick the palm of your hands.
If the clammy hands approach causes your mother to want to call the doctor, insist that everything is fine and pretend, even though ill, you're trying to get up to go to school.
More than likely your parents will tell you to lie back down, but to make sure they think you're a model student who is really sick, you can slip in a comment like "I have a test today. I have to take it. I want to get into a good college, so I can have a fruitful life."
Once again assure your parents you'll be fine and that you just need some sleep and maybe take an Aspirin at noon.
Acknowledge your parents as being nice, caring, and loving people.
Once they leave, it's time to have some care-free fun!
