We found a wonderful woman to be on-call to take our mother to medical appointments, trips to the grocery store, etc. (Our mother is in an assisted living facility, but they don't have staff for this type of help.) My mother really likes her and we have been so pleased. SInce we live elsewhere, we haven't met her personally, but communicate by text message and email when there's a need to do so. Late last week, there was a series of texts/emails among the helper, me and my sibling dealing with what I thought were routine matters (rescheduled appointment, problems with air conditioning, etc.) I was floored to receive an email today from the helper resigning from her work with our mother, because she felt that our emails to her had been "demeaning." I went back through everything. I swear nothing was written with any idea of criticizing this woman --- nothing was further from our minds! --- and (honestly) I can't figure out how what was written could have been interpreted as critical, demeaning, or anything else negative. I quickly responded to her with an explanation of our good intentions, and got an answer saying she didn't want to get any more emails from us. I'm so upset, and I realize that someone that does the kind of work she does, may have been treated poorly in the past. Should I make another effort to get past the communications barrier? Should I let it drop? What on earth could have happened?
