At least 3 times a week at my middle school, a mass e-mail goes out looking for the missing DD. Today, she left class to go to the bathroom and did not return.
She has even tried to lie about being with me a couple of times when she was actually roaming the halls.
Yet, not 1 single genius of a teacher in my building can say - "Hey BB, why don't you escort DD to____________so you can make sure she comes right back to class." Or better yet, tell DD - you are not leaving unless it is an emergency.
