the truth is that of all the people who are important in your life, they're likely the easiest
True that, and not even for the many reasons listed, it's largely because we just don't care. And, I don't mean 'we don't mind,' I mean that we don't give a damn at all. Not that we don't care about you (sort of we do, kinda, not really) but its more that given all the stuff going down, it seems like such a minor and trivial matter to the world at large.*
That why I'll kinda side with the proff here and the dress code - its sort of pretending, and playing dress up like a grown up2 and all that (I'm sure the teacher thinks of it as 'real life training in the world of work' and all that) - because it is the way it works in that real world deal. Whenever I had students complain to me that college sucked and had nothing to do with the real world, I would remind them that, in fact, college sucking was excellent preparation for the real world, which they will find out, also sucks.
In reality, no one is ever going to hire you based on what you wear to the interview. That being said, dressing wrong will assure you that you don't get hired.
One person's fashion, is just costume to everyone else. 'Twas ever thus.
*I've worked for well over a decade now (off and on) with a guy called Brian Warner. Except he doesn't want to be called Brian - guess it's not evil enough, the minions of the almighty prince of darkness are not running around with names like 'brian'. So he calls himself Marylin Manson. And, if you ever want to see the gates of hell open and all the anger of the gods poured out in rage and fury you don't need to buy his records, all you have to do is call him Brian. He's so cute when he gets mad. But, either way, what's it to me?
2 - Though if any student of mine had their mother calling me it damn well better be for some sort of sex hook-up. 'Cause if you still have your mom defending you, well, perhaps college is not the place for you to be. You are not ready for the world of work, I doubt if you're ready for high school. Cheaters on the other hand were easy, I failed them - flat F - as per my syllabus, and as I also said in the syllabus, I did my best to get your ass kicked out of the college. It was kind of fun part of the job, like brutality is for a lot of cops. I did give shelter to two different women at my house for the abuse deal, and helped a lot more without putting myself, my life, and my families life on the line. And I never had a student beat up for coming out of a gay bar, not even in Iowa. (Though I almost gave a few heart attacks when I saw them in there.) Though I had plenty spend the night in the free motel for a DIU, gay and straight.
