I appreciate anyone who correct this text for me. Thank you in advance. Dear friends I need to have this letter to be very formal and polite and I appreciate you if correct it for me. Dear ....... On November 29th, I submitted a manuscript entitled as “.........” for consideration by the "XXX journal ". On January 4th, I received the decision letter asking me to revise the manuscript and resubmit it again. First of all, I'd like to appreciate to the anonymous referee for his suggestions. I have prepared the revision but there is a problem and I so thankful if you help me to find a solution for that. Although I have just taken into account the main ideas in the abstract, the number of words is longer than 250 words (nearly 480 words) and I think all of them are very interesting for the readers. I appreciate you if allow me to have this longer abstract in the manuscript. I look forward for hearing from you. Thank you very much for your consideration Best regards
