Let's try to answer this question. Let's consider some variants, when and why girls do not approach to get acquainted:
First of all, a girl will never come to know the first, if she considers herself beautiful, pretty, pretty. Simply in this case, she is sure that she can easily interest anyone with her appearance, but nothing more. She can only push a little to get to know her (smile, shoot her eyes, flirt at a distance), and in case the young man did not react, then approach him is not worth it, as there are still so many men ready for one look to fall to her feet. The logic of iron - why waste your energy on someone who did not pay attention to you? But this is not the right approach.
Secondly, it is so established in our society that a man should be the first to show initiative and very rarely the girls want to break their established rules by their behavior. This is probably the main reason why the girl herself does not fit to get acquainted. And how will a man react to an attempt to get acquainted? Some men are simply frightened by such girls who are able to take matters into their own hands. The popular belief that a man himself is bound to seek a woman is firmly rooted in the minds of most people. That's why a seemingly cheerful and cheerful girl who, in a usual situation, will not climb into her pocket, fears when, having caught sight of the young man he liked, but not having received an obvious sign of attention from him, she can not decide to approach him first. Or is it not? And suddenly, if he does not correctly assess her behavior, or worse, will she get scared? But it can also be that a young man does not correctly accept this act of the girl and from the confusion still nahamit. Agree, not a very pleasant situation.
Speaking of behavior.
Some men perceive such "enterprising" girls who are able to get to know each other as easily accessible and quite often do not take them seriously. And this is another very powerful argument against such an acquaintance.
There are also such girls who are simply not confident in themselves, in their beauty or in general openly consider themselves unattractive. Such girls especially do not approach the guy to get acquainted even at a distance of a gun shot, so that God forbid not to disgrace himself or cause ridicule of others and the object of acquaintance.
Of course, there are also such people who are completely confident in themselves, they know what to talk about and what to interest, they quickly make various decisions and in general they can easily come up and get acquainted with the first counter. However, women's nature is such that almost all women, without exception, simply adore when they are won by strong, determined and courageous men. That's why they often do not want to get acquainted first, but wait for the man himself to take this step.
Also, with casual acquaintances on the street for girls, there is always the danger of being raped, because you never know who the man who really likes is. It looks so quiet and speaks beautifully, but in the end ... And, unfortunately, such fears are not groundless. Of course, you do not need to get acquainted somewhere in a back alley in the late night, and even sit down in a random car, especially when there is not one driver, but more. But in the daytime, and in bright light, and even in a crowded place. In general, lovely girls, of course, do not overestimate the danger.
Moreover, street acquaintance of you, as a matter of fact, does not oblige you to anything, relations will develop gradually and always, if something does not suit you, you can simply stop them.
Sometimes it happens when a girl is simply sure that nothing like this acquaintance will end. However, think, "nothing good" can end even when you are introduced to a man by friends or parents. From this, no one is immune, and that's life.
And although to show initiative to the girl herself when getting acquainted with a man is still a matter of rather ambiguous and sometimes even "slippery", but from the position of a man, one can say at last: Lovely adorable girls, do not hesitate, be as self-confident and try to act on of the situation. It is possible that the guy you like will do himself, but if this does not happen, do not be afraid to take this very situation in your gentle hands. The most important thing is to be a bit more relaxed, do not be afraid that others will perceive you wrongly, after all, it is quite possible that now you are fighting for your future. Sometimes it is enough simply to say: "Can I get acquainted?", And sometimes it is necessary to invent something more original. Of course, coming up first and starting a conversation, you run the risk of alienating the man you like, even if he is not subject to any patterns of behavior. But here it is probably worth thinking about, but do you need such a man? And remember that by nature a man is an earner and therefore more often than not he wants to be "principal", especially in such a matter as getting acquainted, but that does not mean that you should not take the initiative. Imagine that this acquaintance with a guy is a kind of game in which you simply have to win. Be yourself, sometimes even frankly neglecting the generally accepted rules. Little did you suddenly never see this person again. Paying no attention to anyone, boldly go into battle, in case of your defeat, you will all be left without him. The experience gained, even if not very successful, will still be useful to you in later life, which will necessarily be full of new people and acquaintances.
