Thanks so much Robert! Gotcha. The issue I'm confused with is accounting
for both:- setting the default value (for when no parameter is passed)
and also accepting an input.

I.e. -->

returns "Hello, Master." when say_hello("Master") is called ✔
     Error: returns "Hello, Qui-Gon Jinn."
     when say_hello is called with no parameters
          Error: wrong number of arguments (0 for 1)

Do I use something like a conditional? Something more like the below?

def say_hello(name)
     if say_hello?
         "Hello, #{name}."
     else
         "Hello, Qui-Gon Jinn."
     end
end

Not sure which approach to take.
