You messed with the wrong kid

My daughter has had stomach “issues” for quite awhile now. I am using the word “issues” because we aren’t exactly sure what is wrong yet. The school has a policy that only one boy or girl can use the bathroom in each class at a time to keep them from playing or bullying or whatever. Well I requested awhile back that my child be an exception to this rule due to the medical thing she has going on and they agreed. I got a phone call today saying my daughter was sick. She was in tears because the teacher refused to let her go and forced her to wait until the next class. By the time the next class came around she was in terrible pain and another teacher was concerned and sent my daughter to the nurse. I don’t think I have ever been so angry. My child is an excellent student, she does peer counseling and has never done anything to make them not trust that when she has to go she really has to and isnt off playing in the bathroom. I have always told my kids that if they really have to go are told no that they can go anyway and I will straighten it out later. I think part of the problem was that she is very shy and very obedient and doesn’t feel comfortable going against the rules so she just sits and suffers. I could just strangle that women.
