    Nick and his father are in a train. Nick likes to stand and put his head out of the window. His father says, "Sit down! Don't put your head out of the window! "But Nick goes on putting his head out of the window.

    His father takes Nick's cap quietly and says," You see, your cap has flown. Sit down! Perhaps, your cap will come back. "Nick is afraid and he sits on the chair quietly. Nick's father puts the cap on Nick's head.
