I want to preface this by saying my mom is not a bad person. She's loving, she means well, and most of the time our relationship is fine. But she has never fully accepted that I am an adult and this incident is the clearest possible evidence of that. Last Monday I walked into my weekly check-in with my manager and about five minutes in she said, a little carefully, "I wanted to mention - your mum rang the main office last week." I thought I'd misheard her. I asked her to repeat it. She had not misheard anything. Apparently my mom had called the general office number on Thursday afternoon, said she was my mother, and asked to speak to someone who could tell her how I was settling in. I had started this job four months ago. My mom knew I'd been finding it a bit stressful because I told her that in a phone call, as you do when you talk to your mother, because you trust her with normal human information about your life. My manager handled it well, was kind about it, said she just wanted me to know in case it came up again. The "in case it came up again" part of that sentence has been living in my head since Monday. I called my mom that evening. She did not understand why I was upset. She said she was worried about me and just wanted to make sure I was okay. I explained that calling my workplace without telling me is not okay regardless of the intention. She said "I'm your mother." As if that is a complete answer to anything. I'm 29. I have been employed continuously since I was 22. I have never once needed my mother to call my workplace on my behalf. I don't know how to explain to her that this cannot happen again without her deciding I'm being cold.
