people will ask you, “why did you do X, you should have just done Y!”

and you’ll try to explain that Y would only have been appropriate if the situation was A, and would have been disastrous if it was B, and you were not in fact sure at the time whether the situation was A or B

and then they’ll say, “well OBVIOUSLY it was A, there is no imaginable way it could have been B!”

and then, put in this position, you are forced, in self-defense, to expend the effort of explaining several possible ways it could, in fact, have been B, as far as you could tell at the time (possibilities which you were taking into account when you made the choice)

and then they will glare at you, and say, in a voice barely holding itself back from tearing into you for being such a monumental waste of their time with your made-up imaginary scenarios: “But that’s not how it actually was!”

and then you try, desperately, to get across the concept of how you could not possibly have been certain of that, not with the information you had at your disposal in the moment you made the decision

…but, by this time, your explanation has simply exhausted the human capacity for imagining another person’s thoughts, and all hope is lost
