Well, you check memory very briefly, make a quick scan, and it's awfully easy to say to yourself, Ring, Rang, Rung, and very hard to say to yourself, Pare, Park: they come more slowly.
Tak, rychle zkontrolujete paměť, rychle ji proběhnete, a je velice snadné říct si: "ring, rang, rung..." ale velice těžké říct si: "bare, fort, park...", napadají vás pomaleji.
