In the past I used to suffer people like that all the time. Getting anxious and angry everytime the “phone stalker” called. I would wasted hours on the phone with her in spite of needing to be somewhere or having things to do.
Not anymore. I’m done with that shit.
My partner laughs at me because I rarely answer the phone. The phone, voicemail, and my answering machine are for MY convenience, not the caller’s. I do make return calls, but if someone is keeping me on the phone when I need to go (unless it’s urgent, an emergency, etc) I just tell them,“I have to go, I’ll call you back, have a great day, good bye” It may seem rude but they all get the hint, they’re still my friends and I’m no longer anxious or angry.
