Hi Bob,
This is Alan next door. I’m sorry neighbour, but I have a confession to make to you.
I’ve been riddled with guilt these past few months and have been trying to pluck
up the courage to tell you to your face but I am at least now telling in text as
I can’t live with myself a moment longer without you knowing.
The truth is, I have been sharing your wife, day and night when you’re not around.
In fact, probably more than you, particularly in the mornings after you’ve left for work.
I haven’t been getting it at home recently, but that’s no excuse I know.
I can no longer live with the guilt and I hope you will accept my sincerest apologies.
My wife has known for some time now and I’ve promised her that it won’t happen again.
Regards, Alan.
Bob, feeling anguished and betrayed, immediately went into his bedroom, grabbed
his gun, and without a word, shot his wife twice in the head, killing her instantly.
He returned to the lounge where he poured himself a stiff drink and sat down on the sofa.
He took out his phone to respond to the neighbour’s text and saw he had another message:-

Hi Bob,
This is Alan next door again.
Sorry about the slight typo on my last text, I expect you worked it out.
Anyway, but as I’m sure you noticed, my predictive text changed ‘WiFi’ To ‘Wife’.
Hope you saw the funny side of that.
Regards, Alan.
