Double Standards and Feeling Bummed

To my friend N.Y.F. who was the inspiration for this title (and the winner of our bet), thanks so much.
I had a convesation with N.Y.F. today about double standards. This conversation was about a personal issue, but it ended up including school.
I feel guilty a lot of the time because I don't live a lifestyle my school supports. I teach my kids one thing and then I go home, and many times do another. Now what I do in my own home is not considered wrong by any standards, but I always feel funny thinking about what my students would say if they really knew everything about me.
My friend insisted that having a different standard of living than teaching is absolutely fine. The advice and the lessons we give to our students are based on them as individuals, where they are coming from and where they're going to. As their teacher, I may not necessarily have the same background or ideals. N.Y.F. claims that's 100% ok.
I do see the point my friend is trying to make, but I can't help but feel guilty. I know that my girls look to me as a role model and that they are too young to be able to make the distinction between the way I grew up and their backgrounds. I feel like I'm cheating somehow.
Anyway, I was in a pretty contemplative mood as I got to school. The G.O. had broken out color war, and the kids were screaming up and down the hallways. I was in no mood for that.
The water cooler was empty and the teachers were dying of thirst. That just added to my day.
The 7a class had this great way of cheering me up. We did editorials today, and the girls had such original ideas, and we exchanged funny stories during the entire lesson, I felt so much better coming out of that class.
I knew it was too much to expect that from the 7b. L.K. shot off her mouth about something as soon as I walked through the door, and when I sharply gave it to her, she folded her arms and refused to participate in my lesson. Instead, she tried to stare me down. She had no idea that she was dealing with the person who invented the unbreakable stare. I don't even need to tell you that she lost.
I made a snide comment to G.S. that I was still waiting for her spelling words. She had the grace to blush.
During history, I saw that the class had not bothered to review. I told them to take out a sheet of paper and I gave them a quiz on the spot.
I collected the quiz and tore it up in front of them. I told them that this is what it felt like when I had to prepare all night for their class and they didn't even bother to study.
G.S. laughed in my face.
I told the class that had the principal been there she would've had a lot to say. G.S. commented, "Good, I love when she wastes time."
I looked at G.S. and answered, "Well then, I'm sure she will not mind wasting your time now. Leave my class." G.S. thought I was kidding and refused to go. I waited for her.
After she left, she tried coming back in twice, but I put my foot down and insisted on a note from the principal.
Continuing with history, L.O. asked me if we could go slower. I told her that thanks to her classmates we were behind and that I could not slow down for her. The class groaned, but I think they got it.
I believe I have a love-hate relationship with T.K. One day she loves me and one day she can hate me. Today she loved me because I made copies of notes for her. She's leaving to Israel tonight for a week, and I gave her all the material in advance. She was excited during class today and even raised her hand.
We did editorials and L.K. and F.F. had not done their homework. I sent them both out to complete it. I refused to let them sit in class without having done the work.
The class got the concept of editorials quickly and they also had a great time thinking up reasons to support their opinions.
While they were writing, the secretary came in to ask me what to do with L.K. and F.F. I told her that as soon as they finished their homework they could come back in. As far as G.S was concerned, I wanted her to do history questions until the principal could see her.
The principal came to see me about G.S. I told her what had happened and glossed it in a way so that she would support me.
I told her that G.S had spoken freshly to authority and that she had said a disparaging comment about the principal. I said that to let her sit in class would show the girls that they could get away with being chutzpadik.
The principal seemed to hear what I was saying. I finally learned how to manipulate her and now I'm leaving. Shame, isn't it?
The day was finally over, but I was exhausted.
I walked home with some teachers and we had a lively discussion on the double standards. They were so into the idea. N.Y.F. would've been proud.
I came home, marked their spelling tests, and made up a history review for next week. I feel burned out and slightly bummed. These kids have no appreciation for the amount of work I put into their day. G.S. laughs in my face, L.K. stares me down, and H.W. refuses to write notes. The principal won't take my side, the kids all take advantage, and I still work until two every night.
On a brighter note, S.G.L. and C.O. both redid their spelling homeworks. I'm impressed. Also, my co gave a model lesson in my new school. They seemed to have liked her very much, and now I'm hoping and praying for the best.
So I had a bad day. I'm so bummed.
