I have recently lost a close friend and promised him that after his death i would look after his sister who is in her 80's and has ad. I went to see her today for the first time in 5yrs-(she used to look after me when i was a little girl) i am numb with shock- one minute she knew of her brothers death and then the next spoke about him like she'd seen him yesterday- do i explain to her that he has died when she has 'forgotton' or do i chat happily like he is still alive-because in the next 5 minutes she will be back to normal and talk of his happy times when he was alive- i could tell by her eyes-which mode she was in-present or past! please someone help me-when i told her who i was it was like she had to think for a minute-then something clicked and she remembered me-it was aheartbreaking experience- it is her brothers funeral tomorrow morning-will she remember i went today???
