Well, back then, when you wanted to find out more about the person you liked, you simply had to ask other people. Right now, you do not have to. Because we have the internet! Awesome! All you have to do is type the name of the person you are interested in stalking and then the fun begins!
The question is, however, should you or should you not do that?
Well, the pros are that you will at least find out whether the person is a crazy psychopath or not. And that is a thing which is good knowing before you go somewhere with someone alone.
The cons are, if you find out everything yourself you will miss out on the magic of getting to know each other.
Well, just watch the video perhaps it will teach you more.
