I'm trying to understand this. Just today my dad called me and said, "Well I cut and trimmed the grass and then I did all the laundry and your mother doesn't even know it was me that did it." He said my mom came into the living room after he did all the chores (because he was relaxing for a few minutes) and said, "All you do here is watch TV so why don't you just go home to your wife and stop hanging around here and go watch TV at your own house." Why can't she see my dad's face and another thing, why can't she recognize his voice either? I want to know what is going on in her brain more than anything.
