If you want to lead a nancy bookworm to become neglect from his/her study or make him/her go mischief........................You may ask him/her to chuck his/her books to the trash because............study=fail.........If he do not believe you, you may prove it to him/her......:

Study = No Fail ---equation 1
No study = Fail ---equation 2

everyone agreed this
------------------------------
Then,

Study + No Study = No Fail + Fail
Study (1 + No) = Fail (No + 1)
Study = Fail
(PROVED)


HAHAHA!
Felt a bit guity of doing this stupid stuff!! ^_^
