Why does punctuation matter?

Punctuation matters for many reasons. Punctuation is important because when there are punctuation errors in the text, it leads the reader to believe that there are errors in the writing, as well. Although it may not be true, punctuation errors show immaturity and lack of knowledge, and readers lose respect for authors that contain those simple errors. Punctuation is also imoprtant because it should be common knowledge. Punctuation is something that has been taught almost every year in school, yet some people cannot seem to grasp it. In school, high school especially, if there were too many gramatical errors in a piece of writing, students would start to lose points and their grade would lower. Students should have learned their punctuation for just that reason, but it just didn't seem to happen.
