Penguins are the number-one attraction for many visitors to Antarctica. If you go on a ship that is allowed to make shore landings, you may see them. But to get a close look at penguins, you have to be smart.

First of all, keep in mind that Antarctica’s visitor rules require that you remain at least five meters away from the penguins in order not to disturb them. You could easily become responsible for the death of a little penguin or the destruction of an egg if your too-close presence should disturb a penguin parent.

If a penguin is trying to move away from you, you must stop what you’re doing and back off even if you’re farther than five meters away. However, the rules don’t prevent a curious penguin from approaching within five meters of you — as long as the bird makes the move, not you.

Little penguins, in particular, are quite curious. I’ve seen several lucky tourists who were astonished to find that little penguins came right up to them. If a penguin comes extremely close to you, remember that you are not allowed to touch or hold it.

Here are more tips for getting close to penguins.

Ignore the smell: where penguins live is filled with guano（海鸟粪）and the smell takes some getting used to.

Be quiet because loud noises make penguins nervous. Fast or sudden movements signal meat — eating animals to penguins, and they react accordingly, so slow down when you walk around them.

Since it may take half an hour or more before the penguins get used to you, you need to be patient. Put away your camera — too often people are so focused on getting the pictures that they forget to look with their own eyes, but most of your most memorable experiences in Antarctica will be marked in your mind, not on a roll of films.

   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.
