It is a tribute to a part of her - but in many ways, she was a terrible mother! But we all have our pros and cons :)
However, the effect on me was to remind me of my mother, who, like your mother, took care of me and encouraged me to read, learn, and write beautifully, as was said at that time.
Then the piece has done its job :) Bringing up past memories, both good and bad, give us that chance to reflect and learn, and maybe come to terms with the bad, and appreciate the good a little more. Hopefully, you have a better feeling after reading.
Yes, I have. I understand that there are many facets of your mother, and I acknowledge that some of them were terrible. However, with time, we may forgive, and perhaps we understand the context better.
Of course, we understand and appreciate the good, and we strive not to repeat the mistakes that parents have made in the past. I'm sure you don't repeat those mistakes.
