Giving Erin a lift to the airport the other day, she mentioned the greatest thing about this system is the status conveyed by sporting an A-card. "In essence," she said, "you get to brag about your A-ness."
Of course, this launched an extremely silly conversation in which I then observed that because A-ness is a marketable commodity, I would probably try to sell my A-ness rather than use it myself. I mean, if people want your A-ness, might as well try to make some profit on it.
We moved onto other contexts in which you can brag about your A-ness. For example, in academia, when grades come out. However, offering to sell your A-ness in school would probably get you in trouble. Also, in a pass/no-pass situation, all you really would have to brag about would be your P-ness, which wouldn't be as good as your A-ness, but perhaps better than no-P-ness. And so forth.
I really love my friends.
