You've never had lasting relationships with co-workers?
A significant percentage of my social circle is former coworkers. I still meet up with some that I haven't worked with for over a decade. Or even several decades if you count pre-career jobs.
It'd be pretty weird for me to assume those interactions have to be token interactions.
I've been friendly with most of my co-workers, but aside from the two above, I wouldn't consider any of them "friends". As in we'd never randomly hang out outside of after-work drinks.
