A pen pal is someone with whom you exchange letters as a hobby, but usually have not met. Pen pals are usually strangers whose relationship is based primarily, or even solely, on their exchange of letters. The purpose of a pen pal relationship is often to practice reading and writing in a foreign language, to improve literacy, to learn more about other countries and lifestyles, and to make friendships. While the expansion of the Internet has reduced the number of traditional pen pals, pen pal clubs can nowadays be found on the Internet, in magazine columns, newspapers, and sometimes through clubs or special interest groups. Pen pal organizations can be split into three main categories: free, partial subscription, and subscription-based clubs. Traditional pen pals can be a great opportunity to make friends around the world and have thoughtful conversations.
