<human>: I was travelling through Europe last year and got a fine from the Berlin uBahn... I went out of the downtown zone and didn't realize it so it was the same as going without a ticket... I forgot about until I got some mail sent to me from my parents place and there are several letters from a collections agency demanding I pay them.. I know the ethical thing to do is just pay it... But they are making it expensive and difficult to pay internationally... I have yet to contact them and am wondering what are rammificiations for me living in Canada and if I were to move to Germany with this unpaid fine?? I am asking in terms of my credit rating.

Can you give me a shortened version of the text?
<bot>: I have a fine that's gone to collections in Germany and I live in Canada... If I were to pay what would happen and if I didn't pay what would happen.
