看图写短文,内容必须连贯,提示词:behavior n.行为

图木有看懂,是有人从2楼丢了一团纸然后路人捡起来,放在树下?
One day,a man was passing by a building when someone threw a block of paper from the second floor.The man came forward and picked up the paper.He watched the paper for a while,then folded the paper as a calendar.After that,he put it under a tree where near the flat,then walked away.The one who threw the paper was so curious to the man's behavior,and peaked his head over the window.
