Dear Mr Frens,
Just who do you think you are trying to pass off this photo as being the WKWT photo for March 19? I read this blog every day, and I know for a fact that this was not posted on that day. In fact, the data in the photo (as revealed on Flickr) says that it was taken on the 20th. Just because you claim to have a "serious cough" is no reason to take a day off. Obviously you took this picture on your own MacBook, and don't you dare try to claim that you didn't use your MacBook all day.
My apologies in advance of these complaints.
