Nothing kills the coding flow state quite like a surprise standup with the CEO. One minute you're blissfully wrestling with AngularJS dependencies, finally getting that service to inject properly, and the next you're frantically trying to remember what you actually accomplished yesterday besides "investigating solutions" (aka Stack Overflow rabbit holes).
The sheer panic of having to translate "I spent 6 hours fixing a bug caused by a missing semicolon" into corporate speak while the CEO watches is the true horror of modern development. Bonus anxiety points if you've been secretly refactoring the codebase because whoever wrote it originally should be banned from touching a keyboard.
