Making a mistake or an error of judgement isn't just an act of God or fate or Karma or whatever.
That it happens to all of us is undeniable but the phrases " *** happens" and "we all make mistakes" absolutely do not mean the same thing (or certainly should not mean the same thing in aviation).
If the wind blows a tree down onto my garage it could be argued that " *** happened"
If i decide to try and cut it down, screw it up and it falls on my garage then " I was ***t"
If you had come into this conversation with the phrase "Sometimes we all make dumb decisions that we can't properly explain afterwards" then i think the forum would be overwhelmingly with you.
But to dismiss it with a blase' " *** happens" sounds like you are suggesting that you were not responsible.
S*** did not happen. You did something.
