I have different Latino friends, and they said how Mexican Spanish is more "proper" since it sounds slower. Cindy, one of my Mexican friends, said that Mexican Spanish is similar to the way British people speak English (since it sounds more proper) than American English…if that’s makes any sense. My Puerto Rican friend Julisa and my Dominican friend Gisella said how Dominican and Puerto Rican Spanish are spoken a lot faster with more slang. Is that true?
