Today I learnt it from an American friend. He encouraged my elder son to talk to him so that the boy can brag to his friends: hey, I have an American friend. I told him the answer must be NO. Because the boy is too young to know why and how to brag.

In the real life, many audults would like to brag.I came to an international company as a superviser half years ago. There are many creat ive trainers. They have their own idea about the work. But frankly speaking, they are too low to be professional.But they don't like to be supervised. So , oneday one of my agents have braged to her fellows that she wouldn't follow my order. But she never say it in front me and follow my order.
