Both are so much related to each other. And both are so dissimilar! What are the differences between friendship and love? Is platonic（理想的） friendship possible between persons of opposite sex? Let us try and understand.
两者联系是如此密切，两者却又那么截然不同。友情和爱情有什么区别？异性朋友间的理想化的友谊真的存在吗？我们来试着理解下。

What is friendship? Why do we call a person our friend? When do we call someone a very good friend? If we care for a person, if we are always ready to help that person and if we share most of our thoughts with a person, they are our good friends. We can always count upon our good friends in an emergency. We are always sure that our friend will understand why we acted in a certain way. We need not explain anything to our very good friends. The friendship is so deep and the relationship is so intimate, that most of the things are automatically understood by our friends.
什么是友情？为什么我们管一个人叫"朋友"？什么时候我们管一个人叫作"好朋友"？如果我们关心一个人，我们总是准备帮助那个人；如果我们和某个人分享大部分的想法，那个人一定是我们的好朋友。在紧急情况下我们总是依靠好朋友。我们总是确定好友会理解我们行事的方式。我们不需要向亲密的朋友解释什么。友情如此深，关系如此牢，以致于朋友间的事双方都会很自然地理解。
