I hate Katakana

I cracked a little today with one of the teachers whom is my friend outside of school but whom I strongly dislike teaching with. I asked to see the test she had made. I tactfully mentioned some places that had incorrect grammar. And then I noticed the katakana pronunciation part and I loudly exclaimed "I hate katakana!". It just kind of came out, I surprised myself as I said it. She said "I know but the students aren't motivated to pronounce things correctly so I use it". I was so angry I couldn't speak. She is not letting them learn correctly if they just use katakana. This is the excuse she uses all the time to shoot down ideas and to create an unexciting classroom. She also translates everything I say in class, ensuring that the students can get through a class without actually having to understand any English. Her attitude about the students brings me down as well. I remember last year when we were hiking Ghassan together (before I started teaching with her) she said "the students are so stupid aren't they?!" I don't think she understood that it was a bad thing to say, and then she said it again later. That event properly foreshadowed her attitude when she began teaching again. I don't think she should be teaching. She also told me that my salary is higher than hers and that she doesn't think its fair. (However, she is only a half time worker, so naturally this is the case). And she told me that I should loose weight...fair enough, but rude! The biggest thing that gets to me is her attitude towards students. She has no faith in them. No confidence, yet her tests and worksheets (if she makes them) are ridiculous and she doesn't seem to know what she's doing. I'm not suggesting that I know more than her, I'm just complaining because I don't know how to work with her. When I do the class on my own and stuff, she still translates everything...GRRRRR!!!!!
Also, in other news, I'm starting to get upset with myself for deciding not to go to the Arato bon enkai. The Arato teachers just asked me if I was going to Nagai Kogyo's bon enkai and I said I was. And I think they might have felt hurt because I am not going to theirs and it is a very special, fun event. Well, my reason for not going is silly, I have my Japanese class bon enkai on the same day. However, That bon enkai is kind of lame and nowhere near as fun as the Arato one, but they had asked me first. It probably would have been ok if I changed my mind last week, but now its just 2 weeks away. A few months ago, I was thinking I wouldn't go to the Arato bon enkai because I hadn't been invited to a normal school enkai in a while...but then a teacher told me that the school hasn't had any enkais, therefore, I couldn't be invited anyways! Now I'm a little concerned that I'm making relations with Arato bad because I am not going to their alcohol-induced bonding time. My original thinking was that it wouldn't change anything if I went...but actually I think it might. And now I've already told them I can't go so I need to just stick with this decision and not get upset or worried that I made the wrong decision! No more should have/could have/would haves!
