Dear Abby: Busy retiree annoyed by constant phone calls, late event invitations

Dear Abby: I am a single, retired female. I have a personal side business that keeps me quite busy, and I’m blessed to have many friends. I am also active in community and church events. My issue is that a lot of my friends who are inactive and retired invite me to dinners, the theater and parties, sometimes at the very last minute. Then they become annoyed when I decline.
