Task: Story Composition
Input (English): Premise: I went to buy a new computer mouse. 
 Initial Context: I picked it out and took it to the counter. 
 Original Ending: The cashier tried to scan it, but it wouldn't scan. Since it wouldn't scan, she couldn't sell it to me. I had to go home empty-handed. 
 New ending: The cashier saw what I have done. Since it is not paid yet, they consider it as stolen. I had to go to the admins office because of it. 
Output (English): Acting on an urge though, I slipped it in my pocket.
