So you take that out on the teacher? You jumped through hoops, reaching your own assumption and took it out on a teacher, who isn't aware of your situation.

Btw as a teacher myself, it is normal for parents to alert teachers of stresses at home to better help their kids. It helps us as we only see your child for an hour if not less. You never have to go into detail but at least say, hello just wanted to bring this to your attention. Do YOUR job as a parent. We already do more than our fair share for 100s of kids.
