When a child has been told he is "uncool"，it can be very painful．He may say that he doesn't care，and even act in ways that are the opposite of cool on purpose（故意的）． But these are simply ways to deal with sadness by pretending it's nothing．
    Helping a child like this has to be done carefully，otherwise the child will be guided in a wrong way．If you say "Why are you worried about what other children think about you？It doesn't matter！"，children know that it does matter． Instead，an active way may be best． You could say，"I'm going to do a couple of things to help make school feel better for you．"
    If a boy is having trouble making friends，it helps most if he can be in a school and in a class． The teacher can arrange things so that he has chances to use his abilities to be helpful to class projects． This is how the other children learn to value his good qualities and to like him． A teacher can also raise a child's popularity in the group by showing that he/she values that child．It even helps to put him in a seat next to a very popular child，or to let him be a partner with that child in activities，etc．
   There are things that the parents can do at home，too． Be friendly when your child brings others home to play．Encourage him to invite friends to meals and then serve the dishes that they consider "super"．When you plan weekend trips，picnics，movies，and other shows，invite another child with whom your child wants to be friends．
    What you can do after is to give him a chance to join a group that may be shutting him out．Then，if he has good qualities，he can start to build real friendships of his own．
