Then work caught up to me, and I had to do like four things at the same time, and I wasn't paying attention, and I didn't have time to double check and I...I...um..." he said, talking faster and faster until he just stopped to take a breath. "I put something I wasn't supposed to as one of the pages of the essay by accident, and I was trying to replace it." he said, his ears drooping on his head.
