Attending a lecture presentation@elementary school = 0 yen

I attended a lecture presentation of "What we should do to avoid troubles caused by internet communication" which was held at the elementary school. It was a free lecture presentation. I learned many useful things about internet usage.

Recently there are many troubles among teenagers, such as harass someone. Those are caused by communication through SNS tools, especially LINE.  

The lecturer told us the latest cases and how to prevent troubles. The most of participants impressed about the presentation.
