Hello dot, well I have no wise words for you dot, there aren't any all I will say is tell him to be honest, no good covering it up, it is so sad, all you can do is to be there for your son and grandson, why these things happen is beyond me, life seems so unfair at times, you must also talk about him dot, talk to your grandson, cuddle him and cry with him you can help him and your son so much just by being there, take care dot, I am not religious dot, but I will light candle for the family when I pop down to our little church where I go to sit and think, Ray xx
