　　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 alone. Make friendship a priority (优先). Find the time to be with friends even if it means letting the lawn(草坪)go unmowed(未修剪)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. Keeping a deep friendship requires a level of heartfelt intimacy (亲密). 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. Help raise friends' confidence when they are shaken by a job loss, or other such events.

　　Have different friends for different activities, such as going to the movies, singing in a choir (合唱队), and joining in a bowling league.

　　Don't wait for a friend to ask for help. When a friend has the flu, offer to go to the store or drive his or her children to their after-school activities.

　　Never take a friendship for granted. Like a good marriage, friendship needs care and patience. Become a joiner. Find a group that matches your interests.

　　Talk to strangers. Conversations started in museums, laundry rooms, or bookstores can lead to firm friendship.

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