Usually, the amount of deep subtance found in a person's speech has an inverse correlation with the amount that person speaks. This doesn't apply to everyone. A person sometimes talks a lot, but that person actually has a lot of cool information to share. One of my friends likes to talk, she's very funny, she's very smart, and I actually enjoy talking to her, in part, because she brings out the best in me (in my ability to make fun of people.).
