Some basic differences.
1.Appearance:Polish girls are taller,thinner,have longer legs and more light eyes.They also have more symmetric faces,high cheeks and generally the slavic appearance,a guaranteed quality like let's say Mercedes is for cars
2.Behaviour:Polish girls are more cheerfull,passionate,human,caring and a lot more.
3.Class:Polish girls are more intelligent and reserved.
This is the basic stuff.
Polish girls are more cheerful, passionate, human and caring? Why do you think this?? I'm an American and i don't think any of the Polish girls i know are MORE passionate, human, caring, etc than me. I don't think anyone really has the right to give that sort of assumption. And they're definitely not more reserved..none of the Polish girls that i know could be described as "reserved", and i know quite a few Polish girls.
