Whatsapp blunder

George received a msg on Whatsapp from his neighbour Toby.
The msg read as follows: "Need to make a confession to you, George. I cannot carry the burden of this guilt anymore. I have been using your wife, day and night, when you are away. In fact, I have been using more than you. It might sound as a lame excuse but I have not been getting it at home. The guilt is killing me and I seek your forgiveness. I am really sorry and promise you I will never do it again. "
George, with mad anger and tears running down his eyes grabbed his gun, found his wife in the kitchen, and shot her in the head.
A second Whatsapp msg followed from Toby.
"This autocorrect will be the end of me someday. I meant 'wifi' and not 'wife'."

In his text Traité de géométrie in 1852 Chasles discusses cross ratio, pencils and involutions, all notions which he introduced. Chasles was the victim of a celebrated fraud paying the equivalent of £20,000 for various letters from famous men of science and others which turned out to be forged.
