How many times have we heard this growing up and now that we are "grown up", how many times do we tell this to our own? I keep emphazing this very concept to my daughter (not that she would dare tell her mother a lie) so she will know that mom knows everything and it does no good to lie.
Here is a little story to tell to emphasize this very concept, however you may need to save it till your children are of appropriate age:
Brian invited his mother over for dinner. During the course of the meal, Brian's mother couldn't help but keep noticing how beautiful Brian's roommate, Stephanie, was.
Brian's Mom had long been suspicious of a relationship between Brian and Stephanie, and this had only made her more curious. Over the course of the evening, while watching the two interact, she started to wonder if there was more between Brian and Stephanie than met the eye. Reading his mom's thoughts, Brian volunteered, "I know what you must be thinking, but I assure you Stephanie and I are just roommates."
About a week later, Stephanie came to Brian saying, "Ever since your mother came to dinner, I've been unable to find the beautiful silver gravy ladle. You don't suppose she took it, do you?" Brian said, "Well, I doubt it, but I'll send her an e-mail just to be sure.
So he sat down and wrote: Dear Mom: I'm not saying that you "did" take the gravy ladle from the house, I'm not saying that you "did not" take the gravy ladle. But the fact remains that one has been missing ever since you were here for dinner.
Several days later, Brian received an email back from his mother that read: Dear Son: I'm not saying that you "do" sleep with Stephanie, I'm not saying that you "do not" sleep with Stephanie. But the fact remains that if Stephanie is sleeping in her own bed, she would have found the gravy ladle by now. Love, Mom
LESSON OF THE DAY ... NEVER LIE TO YOUR MOTHER
