An Unfortunate Day

I was pulled over by a police officer today. This was the first experience for me to be stopped by a cop, even in JPN I had never had. At that time, I was so nervous, because I was driving within the speed limit! What the heck was going on? The reason for that is that my licence plate was not updated. I had to update it, but actually I didn't know that because I've never received a letter to let me know running out the limit of my plate. Fortunately, it was not a serious case. However, I do never want to be stopped by police officers, even though she who made me pull over was kind.
