Do you moan and groan whenever a teacher says that you need to improve your grammar? Do you take offense when
 someone tells you that you made a mistake in grammar? Do you feel that studying and learning grammar is boring and
 unnecessary? I hated studying grammar when I was in school. English is a very tricky language loaded with many rules and
 just as many exceptions to those rules. By knowing these rules and exceptions, you'll be a better reader, writer, listener, and
 speaker. Communicating with others is what it's all about.
