Is grammer important?

I think grammer is important because it will help people to get a good job in the future and it shows that you are well educated. When you go on a interview for a job and you speak with good grammer first thing the person thinks is that this guy seems to have a good education and knows how to speak to customers they will hire you right away. When you go to court and talk to the judge and you talk with good grammer it may help of getting out of trouble with the judge or maybe when you get pulled over by a cop
