Do you know what dialog is? If you don't dialog is like a conversation between a number of people. You know, when you talk to someone else, you're using dialog. Dialog is often used in literature. Whenever you use dialog, you need to use quotations around what the person is saying and act as if the dialog is a paragraph. Keep it separated from the rest of the story. In example:
After walking down the street for a while, I noticed my friend Tammy standing in front of the clothing store. I walked in her direction while waving my hand.
"Hey Tammy! How're you doing?"
Tammy responded with a hug and explained how she was doing fine.
