This type of exchange is suitable for langauge learners of all skill levels, even beginners.Because you have a common goal to help each other learn while discussing common interests, you are likely to make meaningful friendships.In pre-internet days, "pen pals" or "pen friends" were friends who kept in touch by sending letters, written with a pen (or pencil or typewriter).Writing was a way for people who lived far apart to learn about each others' lives.Just like in online dating, people are not always who they say they are. You can still connect with a pen friend through some organizations, but the easiest way to start a writing relationship is by looking online.
It is also a great way to improve your writing, reading and grammar skills.
Letters took time to write, and time to travel from the writer's door to the recipient's.
Each letter was a little story, a snapshot of the writer's life at that moment.
It's sometimes easier to share emotions on paper than in person, and a letter can fee like a safe place to express hopes and dreams.
Since the idea is to make a new friend, not necessarily to get a date, there's no pressure. If you're hoping to find a partner by finding a pen pal, you do need to be careful.
