The aircraft doesn’t know if you’ve had a good instructor or a bad one.
Or if you learn differently than other people.
Or if no one ever told you that.
Or if you have too much on your plate to learn every detail that might be relevant.
Or if it hurts your self-esteem to think you might have to work harder than someone else.
Or if you have other issues on your mind.
Or if the timing is poor.
Or if you didn’t anticipate the weather - or even bother to check it.
Or if you are just plain having a bad day.
And it doesn’t care.
