My name is Katrina．When I was nine years old, I often played on my elder brother's waterbed
(水床)．He had a lot of coins and I often put them in my mouth and played with them．
One day, I had one coin in my mouth and the waterbed started moving．As a result, the movement
made me choke(噎住)on the coin．I ran into the living room coughing with my hand around my throat．My mom ran towards me．Before she could get to me, I gave one strong cough and swallowed(吞)the
coin!
I let my mom know that I had choked on a coin and swallowed it．So, she called up my elder
brother and then I was taken to the hospital．It turned out that the coin was right in my esophagus
(食道); it didn't move at all．I had to get doctors to take the coin out．They put me to sleep, put
something with a camera down my throat and pulled the coin out．
Ever since I got out of the hospital, my family and friends have enjoyed calling me "The Human Piggy
Bank"．What an embarrassing experience! Now I still have the coin in a pot! Interesting souvenirs!
