Putting balloons  or speech bubbles on the Page.

The placement of your word bubbles will direct the reader’s eye in which way to read the page. There is one steadfast rule that can not be broken: On the Western Hemisphere, we read from top to bottom, from left to right. Your reader will always read the top-left-most word bubble before any other bubble. Don’t make your readers “guess” which order to read the dialogue. Always make it clear by placing your word balloons carefully.
