Grammar, whether you like it or not, is very important. Often, people will say "grammar is stupid" or "grammar doesn't matter," but often people judge you based on your grammar and you don't even know it. Maybe someone hot like me is judging you, or maybe a teacher, or perhaps a prospective employer. It matters, and you would know that if you weren't so stupid and/or insignificant.
