There is a commercial on TV for B of A where an older married couple is playing a little song on the banjo or guitar or something like that. I didn't even see the whole thing. But at the end, the woman says "we forgot the middle..." She is a little sheepish about the omission, but he acts oblivious, to the point of playing dumb about the whole thing. When she reiterates that they forgot a portion of the song, he responds "nobody is going to know the difference anyway." It is clear that forgetting the middle is the absolute last thing on his mind, or at least that's what he wants to portray.

This is a snapshot of two different mindsets that I don't even believe the producers of the spot realize they have captured. On the one hand, the woman is very aware of the public perception of her performance. I think this is normal and prevalent among most people. On the other hand, the man exudes a confidence, whether real or feigned, that paints him as oblivious to anyone else on this earth. His acceptance of himself and his realization that not only is it likely that no one noticed the minor musical slip-up, but even if they did, it's no skin off of his back. In fact, he'd probably consider it to be their problem.
