So, my mum did go for that reading session, but much later than originally planned. She called me up to tell me she had reached her destination. Also, if I could please call dad up as well, to inform him. Hm.
She continues to say that she tried his mobile, but it was switched off. She looked for the house’s landline number, but it wasn’t saved in her contacts.
Please note that we now stay in her parents’ house. The landline number hasn’t changed for 50-odd years.
I did suggest she could have just dialled it. To which she says: “Oh. Yeah. Didn’t think of that.”
Full points for presence of mind, Mum.
