Language / How hard is it to learn Polish? [178]

Czuję do Ciebie pociąg - I feel a train to you. (I find you attractive)
Zapłata z góry - Payment from the mountain. (Payment in advance)

Language / być pod ręką [7]

It can be used for people, your example would mean something like "my friends are always there for me". However, it sometimes might sound weird, eg. "szef ma podwładnych pod ręką" seems OK, but "podwładni mają szefa pod ręką" is rather strange and it'd be better to say something like "szef jest zawsze dostępny dla swoich pracowników" or similar.

Food / Stuffed cabbage - gołąbki - recipe [59]
