Write a professional email to my landlord asking whether I can make my rent payment 15 days late next month

Mr./Mrs. Landlord, I would like to ask that you allow Brian to turn his rent payment in 15 days late next month.  Please note that he has never had a late payment before and actually has a history of turning his payment in early.  As a matter of fact, if you review all of the previous months and added up all of the days he turned his rent in early, you would find it's a total of 30 days early.  So with that in mind, and considering everything going on in his life right now, he is simply asking to delay his payment for 15 days this upcoming month and then 15 days later you will be receiving the following months payment.  Thanks in advance and appreciate your flexibility and patience in this matter.
