in the realm of possibility

DEAR NEIGHBOR:
Hi, George, this text message is from Richard, next door. I've got a confession to make. I've been riddled with guilt for a few months & have been trying to get up the courage to tell you face-to-face.  At least I'm telling you in this text, & I can't live with myself a minute longer without your knowing about this. The truth is that, when you're not around, I've been sharing your wife, day & night.  In fact, probably much more than you.  I haven't been getting it at home recently & I know that's no excuse. The temptation was just too great. I can't live with the guilt & hope you'll accept my sincere apology & forgive me. Please suggest a fee for usage, & I'll pay you. 
Regards,

Richard

NEIGHBOR'S RESPONSE:
George, feeling enraged & betrayed, grabbed his gun, went next door, & shot Richard dead. He returned home, shot his wife, poured himself a stiff drink & sat down on the sofa. George then looked at his phone & discovered a 2nd text message from Richard.

2nd TEXT MESSAGE:
Hi, George, Richard here again. Sorry about the typo on my last text. I assume you figured it out & noticed that the darned  Spell-Check had changed "wi-fi" to "wife."  Technology, huh?  It'll be the death of us all.
