Keep your tongue clean 

It is not about tongue cleaning. You have to keep your words safe and diplomatic. Badmouthing your old boss will not help you to earn a good mark, it is always better to talk something good about everyone. And try to give a valuable feedback, so that you will be remarked as a reliable person. As your new boss takes in-charge of you, there is a chance for miscommunication. So, be sure you are not talking your boss’ weakness and shortcomings with co-workers.
