    // We have the user's name here [2] in main activity, but, it's stuck in here. We can't access it in our new story activity.
    // Solution:
    // intent can hold a data and pass it to a new activity
        Intent.putExtra("name", name[3]);            //intent.putExtra(Key = "String", value);  // [3]Oh noes, nameVariable is Out of Scope [in different { } { } ]  //Solution: to make our name available to this scope:
                            // Variable Scope:
                            /* To make our name variable available in this new method,
                            we need to either pass it as a parameter to the start story method,
                            or make it a class level member variable,
                            that is available to all the methods in the class.
                            Like, M name field and M start button.
                            Either way is fine, but I generally like to pass things like this as parameters.

                            so add this [3]
                            IF You are wondering why we can use the same "name" for the variable in both scopes, it is again because of scope. These are two totally different scope thus the variables have nothing to do with each other and can be named the same. Because once we are out of this method, the variable will cease to exist.

//What is Key?
// H
