Here's the thing, your child that is bad in school is the same child that hit, bit, threw a temper, straight up bad, when they were a toddler and you thought was cute (and offered no correction or proper training). You and every family member seeing you suffer knows the behavior they get in trouble for in school, constantly, is because they watch violent shows, eat unhealthy, and probably need to cut sugar and caffeine from their diet. It's confusing to them to have permitted a behavior that isn't accepted in school, but allowed (or joked about) freely at home. No one wants to be around bad children and until you correct that behavior you, the teachers, principal, other school members will become real close.

Or you could always home school.

Either way, bad assed children are very costly. Very very costly. I'm gonna say a prayer for you. You are gonna need it. You ain't even half way thru elementary yet!
