 ## Problem
 
-Imagine you are traveling to a foreign country and once at your hotel room you realize your power cord is not compatible with the wall electric socket.
-Luckily you remember you brought with you a socket adapter.
-It will connect to the wall socket on one side and to your power cord on the other side, allowing for communication between them.

 The same situation may arise in code, when 2 (or more) instances (of classes, modules, etc.) want to talk to each other, but whose communication protocol (e.i. the language they use to communicate) is different from each other.
 In such a situation, the [Adapter Pattern](//en.wikipedia.org/wiki/Adapter_pattern) comes in handy. It will do the translation, from one side to the other.
