it's OK for your child to get in trouble sometimes. It builds character and teaches life lessons. As teachers, we are vexed by those parents who stand in the way of those lessons; we call them helicopter parents because they want to swoop in and save their child every time something goes wrong. If we give a child a 79 on a project, then that is what the child deserves. Don't set up a time to meet with me to negotiate extra credit for an 80. It's a 79, regardless of whether you think it should be a B+
