My dad is 86. Lives with my brother who does the minimum to help him. My dad at times doesn't recognize Christopher. Thinks others are in the house, like me or my sister. He often sits weeping for my sister. Who doesn't visit much or care. I started visiting more often but he became defensive. He passed his driving test again and uncharacteristically drove thru a red light narrowly missing an off duty cop. The cop said "u could have killed us' but let him go. My brother was sworn to secrecy. But told me. I told his doctor on the phone in confidence. Dad has fallen asleep while cooking didn't hear the smoke detector and wasn't bothered by the smoke. My brother was alerted and came downstairs. This happened twice. Dad falls often. But gets back up. Doesn't want any help. Or any attention paid to these falls. Became confused about wills and living wills. His lawyer alerted me to this. And we rectified things before any damage done. Dad wants to be left alone. And asks me not to visit. I am of a mind to respect this. What do others think?
