Sometimes on the very first date, having learned a person better, you want to turn around and run away.Why should you continue communication with the person that you're not interested in?
Both guys and girls often suffer from this kind of problem.
It's not enjoyable for guys if meeting is failed, especially on public, in front of other people.
Girls are afraid to take the first step, they are often shy of taking the initiative so as not to seem Intrusive, and the guys are frightened of being rejected and as a result the feeling of self-depreciatory and underestimating of themselves.
In addition to other problems of communicating with people you don’t know, it is difficult to guess whether a person is willing to chat with you.
As we all know, it's usually not easy to learn a person well on the Internet.
