Dear Professor,
Sorry about the mess in the lab. All the animals are gone now. I don’t remember how that happened. I was trying to finish the latest experiment over the weekend. Evidently one of the subjects reacted badly and seems to have bitten me. I don’t remember how that happened. I tried to seal the biter in and start the sterilization. The break in the glass must have kept that from working. I don’t remember how that happened. I think I called out for help from one of the other students. She is mostly gone now. I don’t remember how that happened. Now that as the hour is getting late I have become hungry and need to grab something to eat. If you will stand very still while reading this letter, you won’t remember how it happened.
Sincerely,
Bob
