Homework machine

小菜说：
--I want to create a homework machine. I give it a pencil and a piece of paper. It can write the homework just like I do. I will play piano when it is writing my homework. After it finishes, I will check it.
--What if it did wrong? Will you punish it?
小菜鄙视的斜了一眼妈妈：
--No. I will just let it do it again. I don't punish people.
