I'm looking for advice on how to deal with a boss who doesn't agree that there is no why in feedback. Whenever she doesn't like something (which is most of the time) she tries to be helpful by asking why I (or somebody else) did something or didn't do something etc.
I would characterize her as somewhere between angry and annoyed. The "my boss is angry"-cast gives the advice to stay calm and agree but what do I respond when she asks me why I did something? "Because I was stupid" is generally what she seems to think but it's not a very satisfying answer. To lay out my entire rationale isn't either.
Any advice or questions for clarification are be very appreciated. What's an effective way to deal with the "why?"?
