About the risk of may meet in real, it is one of the important method that strongly decide about “I never meet the people who meet on the Internet in real”.
And understanding about the risk is important too
It may be one of the good way that not make a friend in SNS because perhaps want to meet him.
However even if you do that, of course there is the case of make a friend.
And rather that than there is the enjoyment of SNS.
Then, and if you truly want to meet the friend on the internet, what should you do ?
First, when there are your parents, you will need to thoroughly explain about it and obtain permission
But if you couldn't obtain permission, you should stop meeting no matter how you want to meet.
In the case of obtain permission, you had better tell you parents about what you do and where you are.
