Flowers for Algernon

At the end of Progress Report 9, Charlie feels sorry for Algernon and wants to be his friend.

I asked can I feed him because I felt bad to beat him and I wanted to be nice and make fiends. Burt said no Algernon is a very speshul mouse with an operashun like mine. He was the first of all the animals to stay smart so long and he said that Algernon is so smart he has to solve a problem with a lock that changes every time he goes in to eat so he has to lem something new to get his food. That made me sad because if he coudnt lern he woudnt be able to eat and he would be hungry.
