No malicious intent in tweeting "Wine sucks" -- or so Ms Carmen "Mai" Mislang thinks. The reason she (and most of President Benigno "Noynoy" Aquino III's administration) thinks all's good in the aftermath of this tragic gaffe comes down to breeding. When one sees no harm done in what is an obvious act of rudeness, that indicates the nature of one's breeding.
Ill-bred people do not know better. That is because they were brought up to not know any better.
Ill-bred people are ill-mannered not because they have a conscious intent to be ill-mannered but because they cannot tell the difference between good and ill manners.
Mai Mislang is innocent of any ill intent; that is, innocent by the standards of ill-bred people. Indeed, Noynoy's Malacanang embodies the character of the society that put them in power.
