Despite all my efforts to be as literary as any English major AND writer can be, I am still losing my English. So, now, I am not only losing my Japanese, but I am also losing my English.
But I have excuses! First, I just got back from Japan, and Second, I am reading school kids' essays all day and sometimes using the word "was" instead of "were" sounds completely legit to me. I can't even use idioms correctly. So if you ever hear me say something like this: "... all the Japanese I've learned since now..." just kindly walk me out the door.
I hope there's such a thing as an ex-native English speaker, cuz I am not no native no more.
