My Teacher Made A Sacrifice For Us

It was the first day of the new school year, my second year preparing for the 'A' levels.

Mr Nathan came to class and announced that he was taking over from the previous teacher. He was our new Economics teacher.

Explaining that he was not exactly trained to teach Economics but as there was no other available teacher, he had decided to step forward and offer to take us in Economics, he said:

 I am sacrificing for you.

Then seeing that there was no response from us, he rephrased himself for emphasis:

I am making you a sacrifice.
