# 1. Name of the method
# 2. Does it take any paramters? How many?
# 3. What does it return

  return "Good Morning #{name} :)"
end

# I can call one method many times

# WE WANT A USER INPUT for arguments
puts "Give us your first name.."
first_name = gets.chomp # stores user input to first_name
puts "Give us your last name.."
last_name = gets.chomp # stores user input to last_name
