Here's an example of how it works.
See if this sounds familiar.
You're the husband in this story. Jill is your wife. You're sound asleep after a hard day.
At 4 am, your young daughter's cries wake you.
Your thoughts...
"I'd better get up and take care of her ... but I'm tired, I'm so comfortable ...
Jill can do it ... but she's not getting up ... doesn't she hear the kid? ... I work hard all day,
I did the kid last night ... what's wrong with her? ... I'm a good husband ... she's still not up!
she's being lazy ... she's a lousy mom."
Bang. You've gone from sound asleep to condemning your wife in a few seconds flat.
