LITTLE ROCK, Ark. (KTHV) -- We've all told one at some point in our lives, a lie. But if you worried that someone might not be being honest with you, here are seven questions to ask to detect a lie from Reader's Digest.

1. How is the person speaking? A change in voice can tip you off, but pay attention to how fast or slow a person is speaking and how their breathing.

2. What is the person saying? Liars tend to avoid exclusionary words like "but" and "except", and words like "I", "me", and "mine". Liars have trouble with complex thought processes and want to distance themselves from their tall tales.

3. Is their face giving it away? Some liars may try to hide their feelings with a smile, but there is a flash across their face that can give them away. Pay attention to the micro-expressions that a face can't hide. They are often hard to spot, even trained experts have trouble.

4. How is the person smiling? You can sometimes detect a person's feelings by just the smile on their face. A true smile will incorporate a person's lips and eyes.

5. Does the body language follow the story? Check out the person's entire demeanor as there is no one key feature to give them away. Honesty is characterized by features that are in sync with one another.

6. Is your subject behaving uncharacteristically? Experts believe if someone isn't acting the way they normally are, pay attention. Listen to their speech rate and tone of voice and watch their posture against what you know.

7. Is the question simple or embarrassing? It's normal for someone to look away at a difficult question, but when someone purposely avoids your gaze when asked a simple question, you should be suspicious.
