Making a mistake is normal and is accepted as something usual for humans.
Repeating this mistake, well, it is a little bit irritating.
Repeating this mistake, though you are completely aware of what you do, is bad and unacceptable.
But doing the same, idiotic, lacking-of-sense mistake one more time, thinking on your feet, this is something awful, something that you have to get rid of.
And in case you have found yourself in the lines above - be careful and watch out - your punishment might be closer than you expect.

Think +, I'm all yours.
