The mother-in-law arrives home from shopping to find her son-in-law boiling angry and hurriedly packing his suitcase.
"What happened ?" she asks anxiously.
"What happened!!
I'll tell you what happened.
I sent an e-mail to my wife telling her I was coming home today from my fishing trip.
I get home... and guess what I found ?
Yes, your daughter, my wife, with a naked guy in our marital bed! This is unforgivable, the end of our marriage. I'm done. I'm leaving forever!"
"Calm down, calm down!" says his mother-in-law. "There is something very odd going on here, she would never do such a thing! There must be a simple explanation. I 'll go speak to her immediately and find out what happened."
Moments later, the mother-in-law comes back with a big smile.
"I told you there must be a simple explanation .....she didn't receive your e-mail.
