Begging tips from Stevenson!

I am always on the look-out for fellow letter-writing enthusiasts. Imagine my extreme delight when I found a charming, witty, beggary-letter written from a 15-year-old Robert Louis Stevenson to his father, asking for more money. I found the letter reprinted in the newest issue of Reader's Digest. :) I've shared it for you, below. Take notes, my fellow writers--it's pure genius:

Respected Paternal Relative,
     I write to make a request of the most moderate nature. Every year I have cost you an enormous--nay, elephantine--sum of money for drugs and physician's fees, and the most expensive time of the twelve months was March.
But this year the biting Oriental blasts, the howling tempests, and the general ailments of the human race have been successfully braved by yours truly. 
Does this not deserve remuneration?
I appeal to your charity, I appeal to your generosity, I appeal to your justice, I appeal to your accounts, I appeal, in fine, to your purse.
My sense of generosity forbids the receipt of more--my sense of justice forbids the receipt of less--than half a crown.
Greetings from, sir, your most affectionate and needy son,
                              R. Stevenson
