A small mistake ...
A man received a message from his neighbour :
"Sorry Sir, I am using your Wife day and night, when you are not present at home. In fact, much more than you do... Now I confess this because I am feeling very guilty. I hope you will accept my sincere apologies."
The man took a gun and shot his wife.
A few minutes later he received another message :
"Sorry Sir, spelling mistake: WiFi, not Wife"
