Answer:
No matter in what capacity you are writing a letter of advice, the burden lies on you, to give a positive response. Before responding to such a request you should think about it, but the letter should not be delayed. You should choose your words carefully, do not try to be judgmental. Make the person believe that you really care about him or her and the opinion you are giving is based on the sincerity. If you consider the topic sensitive, you should consider your approach carefully and avoid strong language. Its better to restrict your opinion, to the subject that has been asked do not add other aspects to it.
