In short, to write a good letter you must approach the job in the lightest and most casual way. You must be personal, not abstract. You must not say, 'This is too small a thing to put down'. You must say, 'This is just the sort of small thing we talk about at home. If I tell them this they will see me, as it were they'll hear my voice, they'll know what I'm talking about'.

Good old Mother, he says, 'she is even now sitting at my back, trying at another table to write you a small word with her own hand; the first time she has tried such a thing for a year past.

How simple it is and yet how perfect.
