A Czech diplomat, Saša Mitrofanov, has observed a striking consistency in the style of congratulatory messages sent from Prague to foreign dignitaries over a 45-year period. He is currently comparing two such messages, both sent to celebrate significant birthdays of international leaders. Mitrofanov notes that the comparison demonstrates the lasting nature of certain diplomatic customs and traditions. The messages, while addressed to different recipients across various eras, reveal a remarkable continuity in their form and tone. This observation highlights the importance placed on established protocol within Czech diplomatic practice. The diplomat suggests this consistency speaks to a sense of institutional memory and enduring values within the Czech foreign service. He views this as evidence of the “immortality” of specific characteristics in diplomatic correspondence.
