Not even "not better, just different"

At first, I thought it was kinda cool that I write more proficiently in Spanish than in English. Later, I was ashamed. Then, two days ago I was OK with it. Now I'm back to being chagrined, having just run the spell-checker (something I've never resorted to in my life) over a document, authored by CRG, that I'm translating. Some of my errors are typos, some are Spanish interference (consistently typing en for in), but some are just idiotic: infinite spellings of annhilating, patriarchical, appropiate...
