Do you know how to tell when your child might not be being honest with you ?

The experts say Body Language is the key.
On many occasions, the mouth and the body aren't in sync — the words sound utterly convincing but everything else sends a very different message. Here are six of the most common physical indications of deception. While one or two are likely meaningless, if you see enough of them repeatedly, you should probably be concerned.
Covering the mouth while talking. It's as if they're subconsciously repressing the untruths they're spouting. It may be as blatant as completely concealing the mouth or as subtle as a single finger placed in front of the lips.
Touching the nose. Scientists have found that lying can cause the tissue in the nose to swell, meaning that a quick stroke could be a sign of deceit (or that it's allergy season).
Rubbing an eye. When lying to someone, the instinct is to look away in shame. Since that's a dead giveaway, many people content themselves with a fast wipe of the peepers.
Touching an ear. Just as you're supposed to see no evil, you should hear no evil as well. These nervous gestures can range from a small rub of the back of the ear to an outright yank of the ear lobe.
Going for the neck. Research has found lying can cause a tingling in the tissues of the neck, leading to scratching or pulling the collar. It signals that the speaker is feeling uncertainty, so be concerned if you see it right after you ask your child ,is your homework done. "Of course my homework is done."
Shaking the head no while saying yes. If he says, "Yep, I'm getting home late because I have a big assignment to finish" while nodding his head, he's working 0n a school project. If he sends the mixed message of saying yes while shaking his head no, look for him at the local hang out with his friends from school.
