Such a weird place to look for care and comfort.
Let's grant that an elderly person needs assistance and compassion in this time, and as a community we should provide it. Would we want the bank to provide it? Hell no! There's an enormous conflict of interest there. In this situation I wouldn't want somebody from the bank cozying up to my mom and earning her trust. In fact, I'd go ballistic if they tried. Their financial incentives are to use that trust to persuade her not to exercise her full rights, to avoid her becoming aware of all the avenues of recourse available to her, to make her feel that everything will be okay if she lets the matter drop.
What we really want for someone in her situation, besides emotional support, is a savvy legal advocate who will let the bank know that she is aware of her rights and the bank's obligations, and that she has legal resources at her disposal.
