Can you please teach me how to use a comma? What is that little squiggly line anyway?

Your friend,

This video is all about the comma. Commas are punctuation used to separate lists, numbers, or ideas. We use commas to show a short pause, like just now! Commas can be tricky to learn, so we'll start with commas used in letter writing. Who do you want to write to?
