Heather Gold teaches us how to use "tummeling" in conversation mechanics in this tutorial. When you are having a conversation with someone, you need to know that it is not all about you. You will need to appeal to other people's interests and shift from everything being about you to the other party involved in the conversation. When you are performing or speaking in a large group, you will want to talk like a realistic person and make sure you are not saying something that isn't interesting or is boring. When you do this, you will have more of a response from the audience and have a better time.
