I have just read an article on the internet about a romance forming in the Westminster queue, a young couple who spent 2 days together in the queue, finding they had a lot in common and plan to stay in touch, an interviewer said she felt like "queue-pid" talking to them ! Of course I don't suppose this is unique, there seems lots of friendly banter going on in these groups, platonic friendships forming that will go on long after the Queen's funeral.
There were rainbows outside BH and Windsor at about the same time as the Queen's death was announced, also a diagonal sunbeam was pictured on Her Majesty's coffin as it left Edinburgh. Could there be a spiritual significance in these signs?
