At each stage of your life, you likely have made friends. Some of these friends remain in your life for a long time, while others fall away for various reasons, such as moving, going away to school or arguments. Years later, you may find yourself thinking about some of these friends with whom you have lost touch and wonder what they are up to. If you choose to seek out your long-lost friends, there are many avenues to try.
Search the white pages online to see if you can find your friends. Use a site such as whitepages.com or Yahoo! People Search. Input your friend's name and any part of his address you might know, especially if he has a common last name. This method may not be effective if your friend is female and has gotten married.
Search class reunion websites if the friend you are looking for went to school with you. Sites such as My Life and Memory Lane allow you to search out your classmates. These sites also are beneficial for finding a female friend who may have changed her last name.
