Why do we need friends? Well, having friends may well keep you healthier and help you deal with stress better. Some studies show that people with close friends have a greater ability to fight disease than people who are lonely. But never take a friendship for granted. Like a good marriage, friendship needs care and patience（耐心）.Here is something to remember to maintain（维持）a friendship:

    Make friendship the most important thing. Find the time to be with your friends even if it means letting the grass go unmoved or the dishes unwashed for a while. When you can’t get together, use the phone to keep in touch.

    Open up to close friends. Don’t be afraid to express your inner fears and disappointments. Listen to your friends when they have problems, but offer advice only when it’s wanted.

    Have different friends for different activities, such as going to the movies, singing in a choir, or taking part in a bowling league.

    Don’t wait for a friend to ask a favor. When a friend has the flu, offer to go to the store to buy some pills or drive his / her children to their after-school activities.

    How to make new friends?

    You can start a group, such as a discussion group on gardening or books. Place an ad in a community newspaper to find people.

    Talk to strangers to find new friends. You should be cautious（谨慎的）and use your common sense, of course. Conversations started in museums, laundry rooms, or bookstores can lead to firm friendships.

    Enroll in an adult-education course. A classroom is a good place to meet others with similar interests.
