I know 2 people who will talk incessantly on the phone and hardly let you get a word in edgewise. One is in our church women's group and I care about her but believe she has a personality disorder. I avoid calling her as a rule. The other is a close relative. I am learning that I need to set boundaries, like say "I can't talk over an hour, or until such-and-such time. " I need to fix dinner now; thanks for calling, etc.
