When I was younger I really wanted a pet chinchilla. My parents were against the idea so one night after dinner to stop my questioning my dad told me the reason I couldn't have one was because they were vicious. He explained that a friend of his had a chinchilla and when he went out of town his house keeper accidentally left the lid off of its cage. As the house keeper was vacuuming, the chinchilla escaped and ate her leg off.
For years I believed this without questioning. I actually kept up that belief until a friend of mine mentioned wanting one in middle school. I told her that that was a horrible idea and went on to explain the story. It wasn't until after I had finished that I realized how ridiculous that story was.
