Task: Question Answering
Input (English): Context: I left my phone at home ... with the alarm set . So it 's going to be playing for awhile . And of course , I left the alarm clock on too ... it should only go off for a couple of hours . I feel bad , but not bad enough to drive back home and quiet the place down . Right now , I ' m thinking that another cup of coffee would n't hurt . 
Question: Why did I leave my cell phone at home ?
Output (English): I forgot it .
