Walking home the other day I found two bolete mushrooms I had not found before and did not recognise. After some research I landed on oak boletes, taste test confirmed they were not one of the bitter boletes which was the second most likely species. #fungifriends

I know universities in the UK are underfunded, but paying extra for an exam resit, really? I would have thought administering exams is core business, not an optional extra. I grumble but can afford it, but not everyone is in that position. What if you have to resit an exam for no fault of your own?

If you have a Royal Family, you have deference. If you have a Royal Family, you have a class system. If you have a RF, you essentially say, "These people are better than everyone else by dint of birth & should maintain enormous influence, wealth and power." Why would anyone want that at all?
