The Seven Rules of Communication

Spanish is easier than English, but except for the speed, they do speak quite fast. If someone speaks slowly, it's not too bad if they're using kind of regular Spanish. But man, listening to two native speakers talk to each other,. They're speaking fast and using broken sentences and sometimes slang and it's very, very tough then. Mo mo says, I have a question. Sometimes I meet native speakers that speak very clearly, but it's too hard to understand some speakers. What do you think? What's the problem? Well, it's true because they're not everyone's the same, right?
