This is more of a Ruby thing. You can define optional arguments for a method like this:

def initialize(name="", age=0)
  @name = name
  @age = age
end

By doing it this way, you will be able to call Person.new and then have name default to a blank string if it's not passed and age default to 0. If you want age to be something but name to be blank you'll need to pass an empty string anyway:

Person.new("", 24)
