What handwriting carries that words alone cannot

A person's hand is recognisable across decades, which is a stranger fact than it sounds.

Open a drawer of old correspondence and you can usually identify a writer before reading a word. The slant, the pressure, the way a particular letterform loops or refuses to. That recognition is instant and physical, and it explains why an envelope in a familiar hand produces a jolt that no notification manages. The message has not even been read yet and something has already happened.

Handwriting also records state. Tiredness shows. Haste shows. So does care, in the form of a page written more slowly than usual because the writer wanted it to be legible for someone whose eyes are not what they were. None of this is decoration. It is a second channel running under the words, and it is why people keep letters from writers whose sentences were, frankly, unremarkable.

People who dislike their own handwriting tend to use that as the reason not to write. It is a bad reason. Nobody has ever received a letter and thought less of the sender for an ungainly hand. They think: this person sat down and did this. If the writing is genuinely hard to read, slow down and write larger. That is the whole of the remedy, and it takes an extra four minutes.
