The mother-in-law, comes home and finds her son-in-law furious and packing his suitcase. "What happened, ?"
"What happened? - I'll tell you what happened!
I sent an email to my wife saying that I was coming home from my
trip today. I got home and guess what I found?... My wife, yes my Rachel,
with a naked guy in our marital bed! This is the end of our marriage, I
will leave forever!"
"Calm down!" says mother-in-law.
"There is something odd about this story. Rachel would never do such a thing! Wait a minute while I check what happened."
Moments later, mother-in-law comes back with a big smile. "You see, I said there must be a simple explanation..."
"Rachel didn't receive your Email"
