Әліппе шығармаларды оқып бітірді. Бағанадан үнсіз, бар зейінімен тыңдап отырған. Тілге көз астымен жүрексіне қараған. Риза пішінде жымиып отыр екен. Іші жылып сала берді.
-Шығармалар өте жақсы, - деді Тіл.- Біріне бірі ұқсамайды. Әрі қысқа, әрі нұсқа. Бәріне де жақсы деген баға қоямын.
Например: бітірді - бітіру (не істеу?)
