One of my childhood friends has not responded to my son's graduation announcement. We sent the announcement two weeks before graduation and no card or gift was sent. Her son graduated about 10 years ago and I gave him a refrig for his dorm room and wrote in a nice card. I also talk to this friend freguently as she lives in my neighborhood. I also have been giving her high school daughter advice on getting into college, spending many hours at their house and going over resume building and other ways for daughter to find a hook for college. Recently this friend asked for a donation for a fundraiser that she is involved with and I graciously provided a $100 gift basket for her cause. I finally asked today if she received a graduation announcement from my son and her reply was "Yes, thanks for thinking of us" "How was the graduation?" I am very sad and upset that after being friends for 45 years that this was her response! Should I confront her and let her know my feelings? Or should I just let it go?
