My patience never tried, I got seven changes to spot this time, Or seven ways to die...
Pretty straightforward this one... and very popular too. It seems you really do like this kind of contest.
I asked you to point out the seven differences between the two versions of 'hours...' that I posted. But, don't worry if you only provided six, as I did change it from six to seven differences, which the great majority of you didn't notice anyway.
I think the easiest way to illustrate the seven differences is pictorially, which the image below does nicely... for which, many thanx to Ken Sweden.
