I did the same. It worked quite well even though my mother is a deeply trusting person who sees the good in everyone. I tell her that if she ever has any doubt whatsoever that she’s to call me any time any where and I’ll help. I also promised to cover any financial loss due to eg making a late payment because of my advice.
