Today during seventh period we had a talk about the dangers associated with social network services. We listened to guest speakers from NTT Docomo and from Higashi-Hiroshima police station. They advised us on how to use the Internet responsibly and also on how to protect ourselves in the digital age. The talks were both entertaining and informative. In an age in which more of our lives involve social network services, it is important that we are aware of the dangers and use such sites responsibly.
