DEAR HARRIETTE: I serve on a community board in my city that has done a lot of good over the years. I have had many different roles, and it has been a good run. I am getting older now and want to retire. The problem is that the board is small, and its members are pressing me to stay on. I appreciate the support, but I have had health issues and know that it is time for me to step down. I spoke to the chair of the board recently, and he refused to accept my resignation.
