Going to a new place or a country seems very exciting. We get to know the new culture, trend and meet new people. Somehow we make those people as our friends and try to be in touch with them even after the tour. We add them on social media and in our endless list of friends.
But what if you wanted to prove them that you truly meant the friendship and never took it just as a temporary companionship? And for this, you try to choose 'mailing them a letter'. Well, in that case, you must know their address to send.
