Picture irrelevant, but it is said to be an ancient home in Kashan, Iran (from the Ancient Origins website)
So, I am going to spend the day reading around common spelling mistakes; I was heartened to see that there wasn't many that I slipped up on, but just like everybody else, I do have my weak words eg anything ending in 'ence' and 'ance'. Less common words are understandably misspelt, but it's a case of finding out what they are en route when you are proffreading other people's work.
Suffice to say, there is a lot of prompting and bookmarking going on. I have learnt(and relearnt) quite a bit, so some progress has been made.
