Can I?

As an English teacher I always made a point of trolling my students on the "can I/may I" question. Someone would ask, "Can I go to the bathroom?" and I would respond, usually, with something along the lines of, "I don't know. Have you consulted your doctor?" or "I hope so, or one day you are going to explode!"

I think this pic really says it all though, especially after a student shared with me a pic that stopped short of the teacher's reply to the student's rather cogent argument. The end, is a just criticism of how we fund education.
