Having a companion the first time helps. Remember to smile, speak up, introduce yourself, ask others about themselves, share information about yourself. Keep trying even though you may feel awkward and uncomfortable at times. Go back more than once. It takes time to get to know people.
Friendships develop slowly.
Ongoing contact through phone calls, letters and personal visits is critical. Create opportunities in your own neighborhood. Begin a neighborhood weekly or monthly potluck meal. Get a dog and take it for walks. Organize a small group interested in writing and sharing autobiographies.
