In the previous page we saw the following code.
After defining the method we need to call the method for that method to act.
The way we call that method is by having the name of the instance then a dot and then the method name.
For example when we write biscuit1.eat then it means that we are calling method eat on the instance biscuit1.
When we write biscuit1.gift then we are calling method gift on the instance biscuit1.
If we write just eat or gift then we will get error. Let's see it in action.
The error message is undefined method eat for main.
In summary, first we need to define a method and then we need to call that method to put that method to use.
Just defining the method means that method is ready and waiting for someone to call it to do something.
