Wouldn't be HN without someone taking something far too literally to the detriment of the original point.
How about if we modified the first comment to say "I need you to fix it ASAP"? I can't honestly believe that you'd much rather take someone shouting at you and making you feel bad about yourself, than a direct manager who ALSO speaks his mind, but can do so in a controlled, adult manner.
To me "fix up your shit NOW" is more open-ended, and if the fix takes me a week then that's perfectly fine.
