Southern you are very good. Are you a relationship expert?
I have some experience in women pick up.
You should also take into account the loose slavic attitude towards women.They do not present themselves on the foreground as the Westerners,so it may be more difficult to estimate his level of energy.
Polish girls are also a bit aggressive and choosing men,so he probably expects you to do some steps,to show active interest.Slavic men leave initiative to women,they are not so aggressive,they like natural processes.
