Arriving at the house, he discovered his wife in bed having sex with another man.

Bitterly, Dave kicked them out of the house, and started to plan a course of action.

His thoughts were interrupted by a call from his soon to be ex-mother- in- law.

She believed that there was no doubt a good explanation for her daughter's behavior.

Dave told her to buzz off.

The next day his mother-in-law called again. "Didn't I tell you?" she said.

"Didn't I tell you there was an explanation? I just got through talking to your wife.

She never got your e-mail! It's all your fault!"
