When was the last time you received a personal letter through the post? Not an email, not a bill nor even a postcard.
A letter, maybe running over three or four pages, in finely formed copperplate and covering a variety of topics of mutual interest?
When was the last time you wrote one to someone, excluding the person you love?
Remember the guidelines:
1. Your address top right, begun near the centre of the page [laterally], each new line indented from the previous one;
2. Begin with Dear … and the name, then a comma, that comma then used as the indent margin for all subsequent paragraphs on all subsequent pages [unless the name is so long that this is clearly impracticable, in which case, indent a thumb’s width];
3. Sign off with whichever form you like but only capitalize the first letter in each line, apart from your actual name;
4. Remember that every time you quote, it’s a new paragraph.
