our social studies teacher
My brothers and I often ended up with the same teachers. Our school wasn't big, and we were close in age. I had to deal with their antics.
Our social studies teacher imposed a rule: No eating in class.
My brother raised his hand and asked, "What about water?"
Our teacher said, "OK, fine. You can have water."
My brother raised his hand again and asked, "What about juice?"
Our teacher said, "OK, fine. You can have juice."
My brother raised his hand a third time and asked, "What about smoothies?"
Our teacher was now getting frustrated, and said, "OK. FINE. You can have a smoothie. Let's just agree on the 'no food' rule. You can have whatever drink you want, just no food."
This satisfied my brother. And the next day, he showed up to class with smoothie ingredients and a blender.
