My mother in law is coming up from Mexico at some point next month, depending on when she gets her visa appointment. She also speaks no English. Right now, I'm working on improving my Spanish skills. I've gotten able to pick up words here and there when my wife speaks it with my brother-in-law, who's been at our place for the last couple of months. When he leaves, I should start listening to something in Spanish, probably Mexican news.
I'm also learning to read it better by playing Pokemon Silver in Spanish (it's the Castilian/OG Spanish dialect, but I'll take what I can get) and reading NY1 Noticias. Slowly, I'm gaining confidence. Maybe soon I'll be able to speak it, just need some better grammar and verb knowledge.
