I got an e-mail from my friend Phoebe. I didn't know that she applied to JET last year. She gave me some advice:
"Good luck with JET. Your essay (and Emily's) were certainly better than mine when I applied... and I got accepted as an alternate. Just don't make the mistake I did during the interview and start babbling on about Japanese anime. I think that's what got me downgraded from ALT to alternate ALT."
Thanks for the advice. I don't think it will be a problem though, because I don't know anything about Japanese anime.
