I want to skip school, does this sound like a good idea?

Why don't you just ask your mom if you can skip cl that day? Tell her you want to go to an amusement park and that you will make up all kinds of work and do chores. Seems easier to just beg her to let you off then to get caught lying and ditching. For some reason, parents know everything. Plus, your not Ferris Bueller! Good luck.
