Rails - Apr 2012 - function wrappers // code design

Hello,

I''ve been wondering how to improve this part of code in terms of code
design:

(I''m especially interested in calling the same function with different
default attributes - a lot of code duplication)

def follow_pages(number_of_pages = 5, sleep_interval = 5)
  process_pages true, number_of_pages, sleep_interval
end

def unfollow_pages(number_of_pages = 5, sleep_interval = 5)
  process_pages false, number_of_pages, sleep_interval
end

def process_pages(follow = true, number_of_pages = 5, sleep_interval 5)
  number_of_pages.times do |page|

    sleep rand(sleep_interval)

    if follow
      follow_all_pages
    else
      unfollow_all_pages
    end

  end

end




Thanks for help
