 +==== Interfaces ====
 +
 +A C# interface is a collection of things that we promise to put in our class if we decide to use that interface.
 +
 +Let's say we have a cat. We can make an interface that a cat can implement, but also dogs, and other animals. ​
 +
 +For example we can have an interface called IWalk, ISleep or IEat.
