Dear Annie: What do you do with an old and dear friend who now says something negative at every opportunity? "Lorene" and I live in different states, but used to be in touch daily by phone and on Facebook and have spent time together fairly often when she visits her family here. For years, we were as close as sisters. Then, last year, as Lorene prepared for a reunion with her high school class, she began to change toward me. She hurt my feelings a number of times with subtle snipes and negative comments and, eventually, with a snub that was so insulting, we had a falling out. We didn't speak for some time, but I missed my friend and reconnected with her on Facebook. She welcomed my friend request, but ever since, the snipes and negative comments have been ongoing.
