Everyone thinks thier language hard, with strict rules and pronuciation. Those who teach english, or any language, always focus on rules. In reality, rules matter little to anyone outside classrooms. The ESL students in my class always pointed out my "mistakes", only for me to point out the same techniques being used by the great speakers and writers of history. During years of learning english nobody told them that if you speak well enough, you can do as you wish with rules.
