Dear Grant,
The Advice Columnist is very disappointed to hear about the tough situation you have been put in. We will give you some ways to stop you from being lost. Firstly, since he has been giving you attitude we hope you ignore his acrimony and continue to try to help. Do not let his attitude make you want to give up on him. Once he see that you is determined to help him and is headstrong he will eventually break. Secondly, tell him that it is very unhealthy to starve yourself. You should also tell him that you cannot teach him while he has an empty stomach. Lastly, he may not be paying attention to anything you are trying to teach him because, he has something on his mind that is distracting him and stopping him from wanting to learn. So while teaching him you should use a strategy to catch his attention that will make him want to listen. We hope these approaches can assist you in your situation. Also remember do not let his inflexible attitude stop you from wanting to teach him, be determined.
Sincerely, Advice Columnist
