I haven't written diary for many days. I am becoming lazy.

Today, although hard rain has continued all day, I take Arthur to take his maths class. The lesson is to count numbers over twenty. Arthur is good at counting, and the teacher prized him. Arthur like his lesson, but he is always distracted by his book and pencil.

When I was waiting for him outside, I worked out a maths problem which is hung up on the wall in the center. I gained thirty scores for my son. I hope he would be proud of me.
