Just rang my mum and dad for a chat and Happy Mother’s Day. We got talking about Nazanin Zaghari-Radcliffe being called back to court. I told them about the link with the money allegedly owed Iran from Britain in the early seventies. They then tried to figure out who would have been PM and told me it was Neil Kinnock!!!
I said as far as I am aware he has never been PM in this country. They argued he was and it would be news to him that he hadn’t been! 
What random facts/beliefs do your parents have that you can’t argue (despite knowing the truth)
