The Oldest One of Six
I am very fortunate to have been blessed with wonderful parents. We always were honest and open with each other...even on the difficult subjects of what would you like if...such a situation occurred. My parents were open in sharing what they wanted should a stroke leave them incapacitated or on life support.
I am now trying to inform our "kids" who are adults, of our wants and needs in these circumstances as well. The bottom line is trust. You must have trust in those who will act on your behalf if you are unable to speak for yourself.
If someone appoints you for these tasks,they must discuss the judgement they wish you to make on their behalf. If they don't you must decline the responsibility! As for their care...my parents are ANGELS...they always gave us their very best and we did our best we could under the circumstances.
