Oh that's nice isn't it? And so freshly past the point when you still have to bite your tongue and can't call an asshole teacher a "fucking piece of shit which is you teach high school in the first place" and then follow it up with "how's it go, people who can't do, teach?" because it'll result in getting your fifth of five strikes and kicked out of class for the semester with an accompanying F on your transcripts. Being so soon past that point must have made that moment at the pub feel that much more rewarding (if you were 40 yo and say him you wouldn't have cared much and even if you did enough to say something appropriate, it wouldn't be as gratifying).
