On the Death of Catherine Wellesley, Duchess of Wellington.

Extract taken from her Wikipedia page.

She became seriously ill in 1831, which brought Wellington to her bedside. She ran a finger up his sleeve to find if he was still wearing an armlet she had once given him, "She found it, as she would have at any time these past twenty years, had she cared to look for it" remarked Wellington. "How strange it was", he went on to say, "that people could live together for half a lifetime and only understand each other at the end". She died on 24 April.
