Please give me feedback on my writing from last week. What sdo you like? Is there anything I can improve?

Dear Mrs Turner,

I am extremely intrigued about your son, Matthew.
Matthew, who is normally punctual and always comes to school, recently has been coming very late. Most of the time he doesn’t even bother coming.Because of this, his progress has decreased. Never before has Matthew ever got a level 4.

His behavior is disgraceful. I have noticed that he’s been bumping in to people and ignoring other students from my class.

Matthew, who has generally had a good attitude, now never wants to put his hand up for questions. Usually he takes part in group work but recently he has been lazy and sullen by not taking part and sleeping in my lessons.

I have realized that he doesn’t get along with other members of the class. He is very savage because the other day I saw him kicking someone!
Please write back to me urgently,
Mr Jones
