He had stated that originally he would be taking six months off. I am going to assume that perhaps he changed his mind, and felt the need to return to work to eat up some of the time of constantly thinking about it. Work, is somewhat of a distraction for bits of time.

I can hear the brain dead, insensitive, phone calls now.
