I really do not know. I do try to hide it. I am never bored because I have no feelings or emotions. I am numb. I do stay up very late reading my nook and checking news and political websites (a lifetime ago it seems I used to be a lobbiest). Reading is all I do, but I have no memory or concentration. I guess that is good because I can read the same books over and over and not remember what I read. (saves$$$).
