How something is presented becomes part of what it says. The same handful of words can arrive as a scrap or as a folded sheet, and the care taken in the folding tells the reader they were thought about before the writing began. That is not decoration, it is evidence of attention, which is often the real content. Small physical trouble reads as regard.

When you write something short and meaningful this week, take an extra minute over the object: better paper, a straight fold, an envelope. Post it rather than sending it. People keep the ones that were clearly made for them.
