Today is Saturday.
Yesterday my wife took part in an activity organized by my son's school, which's theme was the ten-year-old anniversary. Only one parent of each student could take part in the activity. My son let his mother to go. I felt a little regret. During the activity, the children shew some programs, such as singing songs, dancing, playing musicals, playing English dramas, etc. Their shows were really amazing and both the children and parents were very happy.
Before yesterday, my wife and I wrote a letter to my son and he wrote a letter to us too. At the last, it came the peak of the activity. The children sang a song of thanks together to the parents and they exchanged their letters. My son told his mother that he was almost moved to cry when he read our letter. He is really a sentimental child. In the letter, my son told us his biggest annoyance was that his score could not satisfy us and he liked the period of the first grade and the second grade. He thought we became stricter to him now. And he wished we could be as kind as before.
My son is growing up. I think we need to have a talk today.
