He's too blunt, too vocal, sometimes unstoppable. Well, at least I notice this unpleasant behaviour early and I am doing whatever I can now to tone him down.
He could be murmuring things like 'do you have any brain?', 'are you crazy?', 'what happen to you,huh?', 'why is he so stupid?', 'why are they like that?', etc to family members especially to his Qo Qo and Daddy. And, at times he would be hurling the same remarks about other people he meets and fortunately these words are not audible to others. Otherwise, Mom would have to turn into a mole for a while and go under the burrow.
I keep reminding him that it is rude to say those things. And nobody likes a rude person as a friend. If he continues to behave rudely, he would have no friends or he would get bashed by someone later. The natural reply from him is 'I don't care!'. That's just his response.
Every now and then, I would tell him that everyone likes friendly and nice people. And that he would get blessings (nice things) if he is good to his friends. This has become a habit to me. Since the past couple of weeks, I have been reminding him, 'Be nice'. Not so good a response from him in the beginning. He kind of rebelled when I said those things. But, I notice some positive changes whenever I say those words. He would look at me, smile a little and just keep quiet.
