Philosophy in a nutshell

It was Saturday evening. We were two sitting in a just two-chaired table sipping a hot coffee. My friend was pleasurably puffing out cigarette. I looked at him, and asked, "Are you interested in philosophy?". He reply with half-comfortable face, "No". I asked, "Why?". "Don't know!", was his reply. "Would you like to know what it means?", asked him as if I knew a lot about it. Then I continued after his positive response to know what it is, "Philosophy is generalization of the set of things you have observed (or experienced)". I saw his pupil dilating. I proceeded saying, "Take for example, we come to this coffee house every Saturday. And we observed that we had to wait very long to place an order, whatever might be the reason: lack of servers. After observing the pattern, we generalized saying that we often get late at this coffee house. After visiting many such coffee shops, we make a bigger generalization that 'visiting coffee shops takes significant amount of time'. Assume that this becomes the philosophy of coffee shops as most agree with that." I felt thankful to him listening to my boring explanation. He looks like agreeing to me. Then I continued asking, "Do u know what perspective means?". I saw him swinging his head sideways. I added continuing the coffee shop philosophy, "People may look at the same philosophy in their own view. That is, different people may have different perspectives (or opinions) on the same philosophy. A person rushing for a work look at coffee shop as a time consuming place. And another person planning to pass time, may think that coffee shop is the best place to be in. The same philosophy, but different perspectives. No perspective is right or wrong, and there are valid reasons for each perspective." I thought he understood -- may be in his own perspective. Then I didn't continue with the discussion, because I didn't want to take this discussion out of the nutshell.
