Welcome to the Punctuation Police, where the commas are always with us and the semicolons are always on our side.
Our mission is to teach you the rules of proper punctuation, because let's face it, you're probably doing it wrong.
1. Commas are not just for commas.
2. Semicolons are for separating items, not just for looks.
3. Colons, on the other hand, are for making statements, not for starting sentences.
