... you know what a Myers Briggs Personality Type is, even without Googling it

... assorted acquaintances and relatives genuinely expect you to be fully expert in whatever quaint technologies are currently giving them problems

... you've had the same PC for well over a decade, with 3 different cases, 4 different PSUs, 5 different motherboards, 6 different CPUs and at least a dozen new hard drives, now all solid state (naturally)

... you welcome the moniker 'geek', whereas other lesser beings may think it perjorative
