Sorry........
A man received message from his neighbour: "Sorry sir, I am using your
wife... day and night... when you are not present at home.... In fact -
more than you; I confess because now I feel very much guilty... Hope you
will accept my sincere apologies".

*... And the man shot his wife.......*

*A few minutes later he received another message : 

"Sorry sir, spelling mistake ... wi fi,  Not wife".*
