Code names are a must:
You can’t let everyone in the world know who you’re talking about, so giving significant people who may be around to hear things a code name is a crucial part of the friendship.
You may not see each other as often as you like, but you must always keep each other updated on all of the current life events:
Texts, phone calls and FaceTimes will get you through your time apart without missing a beat. Keeping updated on each others lives is important for the friendship, and no matter how much you tell each other as you’re miles away from each other, you will always have a whole lot more to catch up on when you reunite.
