Friday's ARW class

We discussed the analogy. It is used when we want to explain something that everyone can agree with. However, we also tend to use it in arguing. Rab explained it to us by giving an example of water versus coca-cola and wool versus nylon. He said water is better for our health than cola, but we cannot say that natural is better than artificial because although wool is natural -made, but some people have allergy to them. I completely understood this story, but I couldn't understand the definition of explain, analogy and argue. So Rab explained to us again by using the arm-wrestling between the old man and young black guy. But I couldn't understand it completely. However, Rab's acting was very interesting!XD
