My dad is 70, my mum passed rather suddenly in 2021. He was a professor for many years, often kept in touch with past students, he adored his job. In 2023 he decided to retire. My sister and I live very far away from him, I'm in the North East of Scotland, my sister is in Cornwall, we both have young families, we try to visit my dad at least once every other month each in London, so he should always have a monthly visiter, even if just for one night.
I have taken a couple of days off work to come and see him this week, he was showing me his Christmas gifts, and mentioned one from a woman I didn't recognise. I asked, he told me she was one of the last students he taught and they have remained friends, she has taken a job instead of pursuing a PHD right now so they enjoy some intellectual sparring.
She is 25, and she isn't from the UK so no family local. He told me he sees her about once a fortnight, often with her charming partner (his words). He mentioned she has a piano and plays guitar and is a beautiful player and singer. They exchange thoughts and any writing they have done, she takes him to talks as he has lost some confidence going out and about alone.
I can't tell if this is something I should be concerned about, or if I should just be glad he has a lovely friend. He has other friends he goes to the pub with.
I am partially worried she might have bad intentions and be looking for money, but I have no basis for that fear.
AIBU to worry?
