Explanation

"Each person is different. For instance, you may be very different from me. And he may be different from you. She may be different from him. And he may be very different from her. It's natural that there are differences. That will always be the case. For instance, you two may agree on something but may be completely different in this aspect. What's more, the two of them may be different from you and so on and so forth etc etc etc. As I said, this cannot be avoided. Differences between two individuals are to be expected. You two may not be able to agree on something, for example...."
"See, that's the thing. Customers differ in their needs. One customer may not always be the same as another customer. In fact, in more cases than not, each customer is different. What I'm saying is that if you take one customer, let's say we take X, here. X is a customer. And then we take Y, here. Y is another customer. X will want something, for instance A. Just for the sake of example, mind you. I mean X may want B also, let's just assume he wants A. Now it cannot be said that Y will want the same thing. In fact Y will be very very different from X, you can take that from me..."
"Take the people sitting around this table, for instance. Let's say X here, goes to buy a car..."
Let's say X runs you over with it. The very different Y and his car, which is undoubtedly different from X's car, are hereby excused from appearing in this analogy.
