There was a set of keys taped to the mirror and a little note below the key . The note read : Sleep an extra 30 . Take my car . My eyes fluttered to the reflection of an obviously unawoken Mike still tangled in the sheets and clutching a pillow .

Question: Who might have left the note on the mirror ?
Answer: I   might have left the note so Mike can use the car when he wakes up .Mike who 's still asleep might have left the note so I wo n't use his car .Mike who 's still asleep might have left the note so I can use his car .None of the above choices .
