Art Critic<br>Allen walked through the art gallery with a focused eye. Every now and then he would stop and criticize a painting. He would disparage every work as boring, dull, and unoriginal. Everyone at the gallery felt Allen was harsh and unkind. When he left, the gallery patrons were relieved.
Allen was cheerful and happy as he observed the works of art.
