With technology, communicating is a lot easier than it used to be while traveling. Now during the times you are abroad, you can not only communicate with your family and friends back home, but you can use programs like Skype and Facetime to see them, as well. Although it may not be the main method of communication, sending postcards and written letters from around the world can be something you keep and look back on to remember your time abroad. I did this while studying abroad in London, and am grateful for the experience.
