Xuan in the eyes of his teacher

Met one of Xuan's favourite teachers today and had a chat with her. She commented that Xuan has always been quiet. He doesn't talk much in the class nor to his teachers. But he is very talkative with his circle of friends. I guess he is like his father, a man of a few words. Hubby and mil once caught him leading his peers to run in the playground. Another day, he gang-ed up with his friends to catch another boy. He probably is a 大哥 among his friends. But the teacher's remark surprised me. I thought he would be playful, bubbly and perhaps out-of-control because that is how he is at home. I maybe wrong, as of now. I shall observe!
