I was using the 'compliment sandwich' as a shorthand for reviewing all the commentary to make sure it's pleasant or polite. That stuff does take effort and time, particularly if you aren't intimately familiar with the other party and have to generalise it to the generic person. I've done a hell of a lot of support in my time and this is abundantly clear to me. There are even people who perform better when you swear around them, because they don't feel like they have to control their language.
Couched phrasing takes effort - and Torvalds is one of the few technocrats who still gets his hands dirty in the trenches.
The closest friend I'm with the more I swear. What I don't get is people awkwardly swearing in presence of people they just met. I see it as attempt to desperately get connection to other people.
Why are you apologizing?
