competent speaker always assumes there is a diversity of opinion and background among his or her listeners.
This is an important factor in everyday speaking or writing. When at work, I can sometimes come off the wrong way to customers and I have trouble explaining myself afterwards. It is important to stay formal but also balance humor, connection, and humility.
One student compared the concept of biogasification to the natural gas production that comes from living creatures like humans and cows. This comparison got a laugh from the audience and also made the seemingly complex concept more understandable.
I LOVE it when people use a comparison that helps the listener or reader gain more understanding. The Pastor at my church does this a lot, and by the end of the sermon, I can understand what he is preaching about. I understand it so much that can go and tell my friend or use that example in a the future when someone asks me a question regarding that topic.
it would be unwise to focus solely on one group over another.
I like the point made in this Chapter because yes it is unwise to do this but sometimes people can try to be 'too diverse' and ramble about 1,000 things in their speech. I find myself in this trap while writing essays for even talking to a friend.
