I remember taking Spanish way back in the 8th grade and the teacher emphasizing the whole gender thing, I think that stuck with me pretty well over the years. Problem I have had over the years is Spanish spoken in different parts of the world tends to be slightly different depending on the country. I've also found that regionally Mexico has "accents" much like the States, had to laugh when some friends were arguing about how huevo was spelled and pronounced, one was from Chihuahua the other southern Mexico. Something for us "Gringo's" to keep in mind when were screwing up another language by speaking it. no es todo bien
