People fall in love. But in the object they are admiring they see their ideal. Then the man is doing his best to fit the ideal's criteria as much as possible, and in the efforts a person is ready to go very far. There are here and there all kinds of tips and advices on how to attract a man or a woman. In any case you should behave with your russian date as with a friend. Jokes and funny stories are welcomed, but potty humor or sex stories you should leave at home.
There is nothing strange in the fact that you on a first date (it is like a minefield for some of us) will be nervous and behave stiffly and unnaturally, all the time thinking if there is anything else to impress the girl. Both dates try to avoid bad jokes or full silence, striving not to seem too interested and too aloof. You may agonize over about whether she feels the same; the excitement and emotions may play the first violin and be so strong that people are not able to connect even two words. After a while it usually passes, leaving the impression, and it depends just on you whether it will be the right one. More often the problem is that instead of your home face the girl you're interested in begins to see the ideal image that you created for her. She won't probably know many things about your personality, your fears, and dreams and so on. And after the ideal "rose-colored glasses" fall down, your girlfriend will likely see the genuine face of yours, realizing that the reality and ideals are completely different things. Even if your date is the most boring interlocutor you should keep in mind that she still deserves your kindness and respect.
The choice of your second half is a very serious life step. And even if your girl seems to be the right one for a role of an ideal partner, it is not enough for creating a happy couple to share all joys and gloomy times through thick and thin. It's an ideal image that you may love easily, but to love the person, whose habits and weaknesses you are familiar with, is much more complicated. But if you love a girl with all her "cockroaches", so the disappointments won't take place after you find yourself fully immersed in a family life.
