Catching a bug while testing is clever. You wrote a good test.
Getting a bug report is stupid. You made a mistake, didn't catch it while testing and actually published it for others to see how stupid you are.
Having said that, I still support the sentiment that most code is buggy. It's futile to expect pervasive perfection.
I was trying to give a reason why people, myself included, don't learn the humility you refer to.
Nice to know it's not endemic!
