Smudge,
I take your point but would add 'people' to 'job'.
During my time I made many acquaintances but just a few long lasting friendships. What I did find, however, is that when these acquaintances resurfaced, the conversation started again where it left off 'X' years before.
That said, about 15 years ago I got back with a group of guys from my early years and now we are all more stable, those acquaintanceships have developed into the long lasting friendships I bemoaned above.
I have often said that there were some people I really liked, some I liked, some I tolerated, a few I preferred to avoid, several I actively disliked but only one I f%^&$£d hated. As that individual is similarly regarded by several people whose judgement I trust - perhaps my unworthy thoughts were actually right!!!
