My 38 year old son exhibits antisocial behaviour - probably has always done but we have never recongnised that it may be an illness. Til now. A perfect example was when a simple family game of scrabble turned ugly 2 days ago. He insisted on trying to use all his letters in one word, despite having a word he could put on the board with less letters. He did not see it as a problem that we had all already waited about 30 minutes and asked him to please put a word down or pass. He just expected everyone to wait an indeterminate length of time until he came up with a word. What do you think?
