Here is our bagpiper. He's the one who will tell you that the time for corrections has come. An invisible friend of us has designed a band of them for our blog, so let's thank him very much. Whenever you see a bagpiper you have to start looking for mistakes as the teachers told you to do. Look for them, identify them and then correct them. Do it before writing the comments for the following chapter. That's all for now. see you
