I am studying "shingle cleaning 101" with a smile on my face. Thanks for being so concerned about me, but you need to focus on your own studies . It looks like you only have 40 more post before you will also need to take the test...

Some guys like to have a little fun, sometimes too much when a question is asked. The answer is in the search function, but for your benefit i will answer it.
