During the two years or eighteen months that you served as a missionary, you doubtless came in contact with many remarkable people. Families you taught, ward members, mission companions, and of course your mission president all had a great impact on your overall mission experience. But once you arrive at home, it seems to become harder to keep in touch. And of course, you don’t want to lose contact with any of these people.
The truth is, it is quite unlikely that you will be able to keep in touch with everyone from your mission. But there are still a few things you can do to better stay involved with as many people from your mission as you can.
While serving, exchange contact info with other missionaries, members, or converts. Exchanging home or email addresses or phone numbers will allow you to write or call these people post-mission. While letter-writing is no longer as popular as it once was, having at least this basic contact information is a start. If you serve in an area where mailing can be unreliable and people often change addresses, it is better to get email or cell phone information rather than a home address.
Use social media. Social media is a wonderful tool that you can use to keep in touch with converts, companions, members, and even (possibly) your mission president. The ever-increasing worldwide use of social media means that no matter where you serve, at least some of the people you meet while serving will most likely have accounts on Facebook, Twitter, Google+, etc. While it is a good idea to not idle away hours and hours on social media sites, you should try to use these sites as best as you can to contact people from your mission. Most missions even have Facebook pages that allow for returned missionaries to keep in touch with each other and receive further updates on the area where they served.
Attend mission reunions when you can. This may not always be easy, depending on the size of your mission and where you are living post-mission. However, whether or not you live close to your mission friends, make an effort to keep in touch with them. If you live in the same area, you can get together for activities or mini-reunions every once in a while. If you attend college in Utah, it is quite likely that larger mission reunions will be held around General Conference. Going to these activities will help you keep in touch with you mission companions or other mission friends.
Don’t lose your foreign language skills! For missionaries that served in foreign-speaking missions, you should do all you can to retain your ability to speak your mission language. After all, if you lose your ability to speak your mission language it will be hard to maintain meaningful contact with converts or native companions. Continue practicing your mission language and take college-level classes if you can so you can maintain the ability to communicate with people from your mission
Keeping in touch with those whom you served and came to love during the mission will help your transition home and be a continual source of joy for you throughout the years. There is nothing quite like a letter that may come years after your mission letting you know that one of your converts has reached the age of missionary service and has decided to serve a full time mission, or that they are going through the temple!
