I Think I Killed Grandma

I'm just an innocent kid, who always got straight A's. I didn't mean it, what I did. I'll go to jail one day. I think I killed Grandma. We went riding on a sleigh, made a gingerbread city, and danced the Nutcracker ballet. What a dreadful pity - I think I killed Grandma. They'll know my identity; with one day to play it cool, I'll finish my gingerbread, then turn myself in at school. I think I killed Grandma. Oh, I'm in trouble, deep. Wait, she's up!  Hurray! She wasn't dead, just asleep. Hey, Grandma, let's play! Oops, I think I killed Grandma.
