Listen to your gut and intuition. You may just know someone is lying. If you are not sure, don't jump to conclusions. Try to get some evidence to back up your hunch. Consider asking directly if the person has lied to you.
Many people feel bad getting caught up in lies, and find it a relief to finally be honest.
Try to be understanding and listen to the person's reasons for lying. Look at your possible role in having someone lie to you. All rights reserved.
