Once, John Constable, a talented English landscape painter was crossing Suffolk, where he lived, in a post-carriage. There were two more gentlemen in the carriage. Constable kept looking at the landscape around and admired it all the way. He kept saying to his chance fellow-travellers, «Just look, how beautiful the nature here is!» The gentlemen were silent, but finally one of them could not help saying, «You must be a clerk or a banker, and you aren't interested in art at all. In any case it's clear you do not go to art exhibitions.» «On the contrary,» replied the painter, «I go there quite often». «Then I can't understand why you admire Suffolk nature so much. Haven't you seen all that on the paintings of our great Constable?» said the angry gentleman.
