TEXT TO NEIGHBOUR:

Hi, Fred, this is Richard, next door.  Ive got a confession to make. Ive been riddled with guilt for a few months and have been trying to get up the courage to tell you face-to-face.  At least Im telling you in this text and I cant live with myself a minute longer without you knowing about this.  The truth is that when youre not around Ive been sharing your wife, day and night.  In fact, probably much more than you.  I havent been getting it at home recently and I know that thats no excuse.  The temptation was just too great.  I cant live with the guilt and hope youll accept my sincere apology and forgive me.  Please suggest a fee for usage and Ill pay you.
Regards, Richard

NEIGHBORS RESPONSE:

Fred, feeling so angered and betrayed, grabbed his gun and shot Richard -- killing him.  He went back home and poured himself a stiff drink and sat down on the sofa. 

Fred then looked at his phone and discovered a second Text message from Richard.

SECOND TEXT MESSAGE:

Hi, Fred, Richard here again.  Sorry about the typo on my last text.  I expect you figured it out and noticed that the damned Auto-Correct had changed wi-fi" to wife.  Technology, huh?  Itll be the death of us all.
Regards, Richard
