And then I met the new coworker, and he was, as far as I could tell, polite and respectful and not awful! When I had first met the previous awful guy and he found out I had way more experience than him, he'd gotten all up in arms and told me that I "had to respect him" and tried to nitpick literally everything I did to a ridiculous extent. The new coworker, when I told him I'd been working at my school for 4 and a half years, responded, "Wow, you must really know your stuff, then!" When Japanese coworkers, including the principal of the school asked the previous asshole guy to do anything, he'd say "WHAT?? Speak English!!" and argue with everything they asked of him. The new guy was very careful to be polite to my coworkers and do whatever was asked of him without getting in the way or being a bother. I don't really know anything about his personality and I don't think we're going to be best friends or anything, but I already have a positive impression of him. It's amazing how much just a respectful and polite attitude can get things off to the right start! (Also, as an aside, it's amazing how horrible and entitled and generally gross some foreign people can act in Japan.)
The horrible class was maybe slightly less horrible than they're fully capable of being, and then the parent observation class went fine, and randomly, one kid ran up to me outside of class announcing, "Everyone's talking about how Miranda-sensei is really good at kanji! Actually, katakana, hiragana, and kanji, the rumor is that all your writing is really neat and good!" Which was really cute, and made me feel good about myself. XD I'm not sure where this "hearsay" came from, but I was flattered, especially coming from a ten year old who really clearly was just saying it with no ulterior motive, and not trying to suck up to me, or anything like that.
And then I came home and watched the Emma PV a bunch of times, so all in all, it was actually a pretty successful day! I'm exhausted now, and ready for the weekend, but I'm glad that I was able to get through this day!
