   Friends should always be honest with you, right? So when they lie, it can  be really hard to take. You want to trust your friends and that means knowing that they'll tell it to you straight no matter what it is. But a friend who lies isn't always trying to hurt you. Why does this happen?

Protect your feelings

One of the biggest reasons friends lie is simply to avoid hurting your feelings.

Some people don't understand the difference between being gently honest with a friend and being so straightforward（直接了当的）that they leave a verbal wound. They choose to avoid these two extremes in the form of a lie.

What you can do: Encourage your friends to be straight with you. No matter what their answer is, let them know you are grateful for it.

They feel embarrassed

Sometimes friends will lie about things in their life because they are too embarrassed to admit the truth. Maybe they are going through a rough time and they just don't want you to know about it.

What you can do: Avoid trying to badger（纠缠）your friend into telling you what's wrong. Instead, make it clear that you are there for them when and if they are ready to talk.

Avoid an argument with you

Perhaps your friend knows that if they tell you the truth, you'll get angry with them. Avoiding conflict is not always healthy for a friendship because it allows problems to grow over time. If you have a bad temper（脾气）, your friend might try and avoid getting into an argument with you and instead just tell you what you want to hear.

What you can do: Make sure that if a friend tells you something unpleasant, you don't overreact. Consider what's being said and why your friend is telling you this. If you do end up arguing, do it in a respectable way.

Exclude you

Lying isn't always a sign that friends are trying to protect you, however. Sometimes they lie because they want to exclude you from their plans.

What you can do：When you find out with certainty that your friend is lying to you, try and face it. Be forewarned, however, that if a friend lies to begin with, he or she may lie when asked a direct question about his or her dishonesty. Go with your guts on this. If you feel your friend is lying because he or she doesn't want to be around you, that's your wake-up call to move on.

   Over the years, I've received a lot of advice from friends and family, trained professionals and books on how to get along with others and build strong relationships. Most of it is insightful（有见地的） and effective but when I'm caught up in the moment, I find it hard to apply what I've learned. This is especially true when it involves a multi-step process.

After analyzing many methods and experimenting in my own interactions（交流）, I've found one simple guideline that has helped me strengthen every one of my interpersonal relationships. This simple easy-to-remember tip is: Make the other person feel important.

No one likes to feel small and most conflicts（冲突）occur when you make others feel unimportant whether you plan to or not. The key to getting along with almost anyone is to avoid actions that diminish others and replace them with actions that build up others. Actually,you can strengthen your relationships with many actions.

When you interact with someone, give him your undivided attention. Don't look around to see what else is going on or check your phone or watch. Take time to listen and respond  accordingly to show  you're engaged. Make the other person feel like he is the most important person you’re meeting with.

Nothing will make someone light up more brightly than showing genuine interest in him. Be curious and ask specific questions based on what you hear. The more questions you ask, the better the interaction will go but keep in mind that you must be sincere. If you try to fake it, people can tell.

When it is possible,show that you consider the other person remarkable. Find opportunities to speak highly of this person to others as often as you honestly can. One trap to avoid is making others feel  more important by putting yourself down. This is never helpful so it's important that you lift others up in a way that respects everyone including you.
