My daughter is in her mid-20s and an incredibly deep thinker, she studied philosophy, religion and ethics and a MA in philosophy, she is considering a PhD. She was baptised/first communion as a child but we've had little engagement with the church lately, she however has returned, goes to mass often but not weekly. She is incredible, and I am very proud of her, but she never seems to be able to approach a topic lightly. It makes me dread phone calls as seemingly the most basic conversation can be turned into philosophy, theology or sociology. She isn't forcing a belief on me at all more so she is inquisitive, the adult version of a toddler who can't stop asking why and loves to play devils advocate, or have deep conversations about a totally abstract topic. In particular she loves to discuss how different philosophical schools of thought intertwine or compete with religion, the theology of various Christian denominations and the roots of breakaway churches/schisms. I often ask for a lighter phone call just about her life as she has friends and is social and sporty, but after a brief overview it always goes into ... and we spoke about this, followed by her asking questions on my thoughts on the topic. Even discussions about books go far deeper than I can handle. She also does it with sport, we both enjoy tennis but I can never just comment on a match without it turning into a conversation on the sociology of women in sports, the psychology of competition etc.
All that's to say I find it exhausting, if she were just sharing her thoughts I wouldn't mind so much, but it often comes with lots of questions such as what are your thoughts? Why do you think that?
Today we met for lunch and she told me it makes her sad I don't show the same interest in her interests as I do her brothers or call her as often, I explained why and that her brothers are more content with small talk so I find calling them requires less mental energy, she apologised and said she doesn't know how to turn off the deep thinking. She has a long term boyfriend who seems to be interested in the intellectual sparring so I'm not sure why she is so keen to get it from me.
AIBU to find this exhausting? How do I handle it before it damages our relationship?
