What I think of Grammar?

Hmmm.. For me, Grammar is an important thing but it's hard to learn. I had been learned English for 13 years and above, but my Grammar still very bad. Grammar does not only know how to speak, we still need to know what the system of it is. I think a lot of people will hate the Grammar (including me), because it’s really annoyed! But I can’t refuse to learn it, Grammar is useful for everything, it build up the rules and frameworks, changing the form of words and joining them into sentences. If no Grammar, it will cause problems on communication and so on. So, I need to try my best to learn Grammar!
