I taught 11-12 year olds for 2 years, and it wouldn't matter male or female, whatever...if I saw them walking down my street doing that, I'm going to think BIG PROBLEM.
What "use to be the norm" IS NO LONGER THE NORM.
As far as the use of the word "thug"...teenagers today see that as a plus. They write it on their knuckles, I see it on the bookcovers, their back packs, they write it on their tests just doodling, it's written in the bathrooms, on the desks, on the school itself it is in the music they love. "THUG life" is the life, it's cool. And I would almost bet money that if we could read that young 12 year old mind, "thug life" was in it, or a song, etc....and he was "playing" YES PROBABLY, pretending to be living that word that you said not to use. I've been teaching in an demographically urban school for 24 years, kids of yesterday are NOTHING like the kids of today.
