You don't. You're at school because its your JOB to get an education. You save the FB thing for AFTER school! If I was your folks, I'd take your cell phone away during the school day & only give it back to you when you get home from school to prevent this kind of thing. Hopefully your school has that website BLOCKED on their puters. Your folks are paying for you to go to school-how about giving them their money's worth instead of flirting & showing your @$$ on FB?
