Love / Why the Polish girls are not laughing? [22]

Hello everyone!

I'm Fabio and I'm a Italian traveler that loves Poland.
There are so many things about Poland that I love such as Polish food and Polish people in general. But, when I went to Poland last January (Krakow), I noticed that so many people are not laughing, especially girls.

I don't think I'm crazy.

Why the polish girls are not laughing?
