I didnt mean you..... The psychologist said it
The rest of the Hm's cant be arsed having a conversation with Sam because it is too much hard work for them,and if you mainly ignore someone you will think them dull & bland.
He has found someone who will give him the time of day & who will include him in conversations. I personally think it is a genuine friendship on both parts.
