Today is Monday.

It's the school opening day of my son. I was disappointed with him yesterday, because he hadn't finished his homework yet. He told me he could in charge of his winter vacation homework by himself, but when I checked yesterday, he let me down. I had been asking him if he had finished all of his homework before yesterday, which I had turned him off. I had imagined this result, but when it really happened, I couldn't help feeling disappointed. I was not angry. I just felt upset. I wanted him to be a responsible person, but I really doubt now. I don't know who should be blamed. I think It's me who made the mistakes. I am not a good father. I don't know how to teach my son.

I am really disappointed with myself.
