I had so much work to do today at work that I had no time for anything! Marzena came by to help me out and I was so grateful that she had time to help me that as she was walking back to her desk I shouted "Dziękuję!"
Later I told her I really, really appreciated her help so I asked Jak to powiedzieć ...Thank-you very much?
To which she replied "Dziękuję bardzo". (jen-koo-yeh bard-zo)
