A man received a message from his neighbour … :

Sorry sir I am using your wife… I am using day and night … I am using when you are not present at home…. In fact I am using more than you are using… I confess this because now I feel very much guilt…

Hope you will accept my sincere apologies !!!

… And the man shot his wife…

Few minutes later he received another message :

 Sorry sir, spelling mistake … ***wifi*** not *wife*
