In third grade, back when I wasn't aware of me being a furry, we were playing kickball outside on the gravel, and my friend John was up to kick. He kicked, missed, and flipped backwards and smashed his head on the concrete. In pain and unconscious, our teacher immediately called the ambulance. A doctor stated he just had a concussion. As my teacher's eyes lit up, our eyes filled with joy, knowing that he was in no serious harm. However, after coming back to school, he didn't recognize us. We stared at him strangely, first questioning if we had gone crazy; then wondering if HE had gone crazy. He apparently had a bit of short-term memory loss, and later came to his senses soon after.
I have a HUGE habit of telling my life stories like a book.
