　　When it comes to the experience, the most impressive memory in my mind was happening in last summer.

　　During the holiday, I stayed at home alone and I was so addicted into playing mobile phone, which sometimes can make me bored to death. One day, suddenly, I wanted to find a foreign pen pal on the Internet. It was a coincidence that it's the first time I knew the website called PenPal World. Then I used my phone to register an account by instinct. After that, I uploaded some personal information and my email address. Finishing, I started to browse others' home page in order to find more fascinating and excellent pals.

　　I was attracted by a Belarus boy's introduction and his smile looks like an angel, and I saw that he can speak fluent English, Russian and German. I was so amazed by that he also had gift in playing musical instruments.So I pressed the button and sent an email to him and asked him some questions about how to acquire more skills in a short time. It was so amazing that he replied me an hour later and he was so nice to answer all of my questions in a gentle way. I was touched by his behavior, I mean, I was a totally stranger to him. So it's just organically happening that we became pen pals.

　　From that moment on, I was so delighted to use my mobile phone to check my mail box. It was quite a pleasure for me to share my happiness and troubles with a stranger. I felt so magical to get in touch with a stranger through my mobile phone.
