If you fuck up, just own it. The reaction will almost never be as bad as you think it will be and it’s always better to be straight up than hide it, cause if it swings back around you’ll be embarrassed.
I don’t know why so many people feel the pathological urge to point the blame at literally anyone other than themselves. Admitting fault is a strength, not a weakness. If you tell me you fucked something up I’ll respect you so much more than if you deflect and try to point blame.
