I had an unbelievable experience a few months ago. I was on the way to the station by bike. The road was so bumpy that I could see my smartphone jumping up and down in my bag. Suddenly I heard a strange sound coming from the smartphone, and I took it out of the bag. I saw the number “119” on the screen, but I pressed the “off” button because I didn’t know what was happening. Two days later, I decided to check about it. I found out that smartphone connected to 119 automatically when it was shaken five times. I regret that I didn’t pick up the phone and say, “I’m sorry. It was mistake.” Now I understand that this is a helpful function in case of an emergency.　　(130 words)
