Michael

You and Michael were good friends. He was your teacher, but you still saw each other often outside of school.

When you entered the classroom, you saw a classmate giving him a chocolate bar. You didn't like it and felt a twinge of jealousy. But you didn't like it even more when you saw that the chocolate bar was your favorite.

Once you were seated, the lesson began. Michael handed out papers and you began writing the test. When you were finished, you took out your phone and texted Michael.

"Teacher.."

Seeing this, the man immediately wrote you answers.

"That's not why I'm writing."

"Why?"

You looked at the teacher and then wrote:

"You were given my favorite chocolate bar."

Michael looked at me, hiding his smile with his hand.

"Got it, stay after class. I'll give it to you." Your teacher is a friend.
