Teacher addresses a student and asks: "How many kidneys do we have?"
"Four!", The student responds.
"Four? Haha," The teacher was one of those who took pleasure in picking on his students' mistakes and demoralizing them.
"Bring a bundle of grass, because we have an ass in the room," the teacher orders a front bencher.
"And for me a coffee!", the student added.
The teacher was furious and expelled the student from the room.
The student was, by the way, the humorist Aparicio Torelly Aporelly (1895-1971), better known as the "Baron de Itararé".
On his way out of the classroom, the student still had the audacity to correct the furious teacher:
"You asked me how many kidneys' we have. " 'We have four: two of mine and two of yours. 'We have' is an expression used for the plural. Enjoy the grass".
Life demands much more understanding than knowledge. Sometimes people, because they have a little more knowledge or 'believe' that they have it, feel they have the right to underestimate others.
