A student's feelings

When a student is late for class
He is not punctual
When a teacher is late for class
She has so much work to do
When a student has not completed his work
He is irresponsible
When a teacher has not completed her work
She is not a machine
When a student cannot explain something
He is ignorant about studies
When a teacher cannot explain something
It needs no explanation
When a student bunks a class
He is not serious about studies
When a teacher does the same
She needs a break
OH THESE TEACHERS
