After 23 years, some 5 of which were for one particular IPT; my junior Flt lt asked me to put some words together for my valedictory letter. This I duly did, and emailed back a couple of days later not expecting any of my words to be present on the letter should I actually receive it! Two month after starting with my current employer, I received not one but 3 leaving packs from the omnipotent JPAC, each of which contained a valedictory letter with surprisingly exactly what I had written.
