When I was younger I had a Russian Blue cat named Bowser. He was a very thick, stocky cat who constantly demanded cuddles, and would punish me if I didn't meet his daily quota. When I was 10, I left my homework unattended for a few minutes while I ate dinner. When I came back, the homework page had a very big chunk taken out of the side.
The next day I was questioned about this by my teacher. All I could say to her was, "Would you believe me if I said my cat ate my homework?"
OK, I think I can top that, and this is totally true. I swear. When I was in my early teens, we had to pay for a library book that our dog chewed up, and for all practical purposes, competely demolished. The name of book: "How to Obedience Train Your Irish Setter."
Once, my dog ate my homework. The teacher didn't believe me. No one believed me.
