Yesterday, I went back to my hometown. While I was going out to buy my lunch, I found out my bicycle was gone. I thought it was stolen several days ago. Because it was sort of worthless monetarily, I did not take any measures to preclude it from being stolen. In other words, to steal it was quite easy. I did not think people would have interest in it but it did be taken away. Now, I buy a new bicycle and I have to take some measures to preclude it from being stolen. Since something sort of monetarily worthless could be stolen, I dare not deal with my new bicycle without any protection!
