Death of the old

Going past the joking banter Daisy and Edward were having, they began their tutoring session in full swing.

The two girls were very clever and quickly figured out about the numbers. Edward felt that this might be related to human beings having ten fingers which made it easier to learn.

At one point Daisy had suggest some kind of a reward for every time they correctly learned something. Edward had realized things were heading towards dangerous territory but before he could interrupt the duo, they had already agreed on the idea.

Everyone time one of them learned Edward's instructions or answered his questions correctly, they would be rewarded. 

And the reward, which Daisy had suggested was very troubling for Edward although he enjoyed it as a man.
