The Difference Between Programmers And Testers

Programmers solve problems with pure logic: subtract your age difference (2) from your current age (44) and boom—sister is 42. Clean, efficient, and completely wrong.

Meanwhile, testers exist to find every possible edge case that could break your solution. What if she died? What if she's traveling near light speed? What if your mother had an affair and she's not even your sister?

This is why your QA team keeps rejecting your "perfectly working code." They're not being difficult—they're just doing what Harvard students apparently do best: overthinking simple math problems until they become existential crises.
