i was specifically chosen for this task because I’m a longtime trusted friend that, as my friend said “understands the assignment, knows when to make the most important decisions.”Her words and I agree, so did my parents and I was their youngest child.
You tell them that they are out of line, and this isn't their business.
You can dress this up nicely or not, dependent on their approach.
Give you two instances:
#1. Irma, your friend's OTHER friend says "Oh, Fad. This isn't the right place for ______ (your friend. This place is awful!"
You would reply "Irma, __________(friend) trusted me implicitly in being her POA and I am fulfilling her wishes to the best of my ability. This really is my business, and isn't open for discussion."
#2 The much nicer friend of your friend says " Fad, are you pretty sure of where _____ is now?"
You say "Much nicer, I am doing as I think best, and it isn't something I as POA am free to discuss with anyone else". Big smile.
You will have here total freedom. Look them straight in the eyes with a stare that says loud and clear "YOU will NOT go HERE again".
