There's a thing where you know you really speak a language fluently when you're no longer translating in your head as you go. Today I found out I'm not there yet. I was talking on the phone with a potential housekeeper (I know, right?) I told her that our apartment was on Defensa Street. And she said, Defensa with a "D" as in "finger"? And my head briefly spun, and then I said, Oh of course yes, D as in finger.
But aside from that part the whole exchange was pretty comfortable on my end. Progress!
