Disparity of foundations

Another common problem of nowadays. This world, the world we live in today is a world deprived of all boundaries. People from all over the world have an opportunity to reach any person they want and to get acquainted with him or her. No need to talk about means of such boundless communication as those means is not the question we bother about. The question we bother about is of different nature.
The question we bother about is the consequences such communication is pregnant with. People of different countries and cultures meet each other, they fall in love with each other and sooner or later the desire to spend the entire life together appears. There is nothing wrong in that desire, though such people will face a number of difficulties. The main difficulty for them will be the difference of foundations.
For example, it is common for some modern countries that women themselves pay their bill at the restaurant. In case if man will show the desire to pay her bill, he undergoes a risk to offend a woman. Though, there is also great number of countries in which it is common for man to treat a woman. And a man who won't do that will be recognized as a man of bad form.
This is the differences of foundations. Those differences create a number of problems for people. Such couples sometimes fail to realize that the foundations are a problem of their relations, but not the character of their couple. It will take great amount of time and patience for such people to deal with disparity of their foundations. They can bring some changes into their characters or just take thins as they are.
