"Dear Vicki: My sister and I have been pretty close most of our lives. But we’ve taken very different paths. I went to college, then accepted a managerial position with a local bank. Genni worked as a nurse’s aide, which she loved. Several years ago, Genni married an accountant named John and it’s been a good marriage for her. Early on I realized that my brother-in-law was a controlling, opinionated person and have dealt with that for Genni’s sake. However, almost a year ago, John’s mother (another very opinionated person) became quite ill and moved in with Genni and John. Since then, Genni has really changed."
