Different nations, different mentality and attitude to leading life points.
It is so difficult to realize and take it the way it is, cause we always treat other people the way we understand is "good". Being different is important to go on compromises. That is what people do, mostly. But there is also another side of the coin...
Compromises are fine, but what if the compromises, which we are doing, are also with the colour of our individual attitude to the situation? To one nation this "stuff" is O.K., to another it is not understandable, and so on. What kind of compromises are needed then?
There are also different kind of people - some are fast-decision-makers, some are slow. For some people 1 year is a huge life period, for some it is just a piece of sand in hourglass. It is quite heavy to build life with a person who is living with another tempo than you.
Another point is traditions and cultures. Who can understand the importance of stuff which is close to one's heart, if for another person it is just a prejudices or just a "bullshit", which does not worth to spend energy on.
Compromises? There is probably an interlayer of respect missing... How to deal when these two, who can't understand each other, always bend each other? I bet one will break soon... it's physics.
O.K., but what if one decides to change himself and will erase all what was given with mother milk? Will this person stay the same, as before? Will he/she become better? Probably not. But who knows, right?
Anyway, if two different people fell in love with each other, it means there was a reason! And maybe they even got this feelings cause of this difference? When will people start to love each other, being true, the way we all really are? Without a wish to change or to force something...
