Quote from : White Teeth Book

Now, how do the young prepare to meet the old? The same way the old prepare to meet the young: with a little condescension; with low expectation of the other’s rationality; with the knowledge that the other will find what they say hard to understand, that it will go beyond them (not so much over the head as between the legs); and with the feeling that they must arrive with something the other will like, something suitable.
