Ran a search in Russian. Couldn't find anything.
I don't know of any special or hidden meaning.
Most Russian poetry is a bit on the dark side, though.
That sounds like something she got locally so it really wouldn't have much Russian influence.
The question is, did the Polish girl get you a card, too?
If both the girls got both you guys cards, then it might not mean anything. But if only the Russian girl got you a card it might.
The two girls would have talked about it. And if only one of them got you a card, then the other was probably getting out of the way. One wouldn't want to be outdone, unless there was a little something 'extra' going on.
Might not be much extra, but it's an opportunity.
If you're worried things could get strange, you could show her the card, say spasiba (spa-SEE-ba) and ask if it means she's going to be your anti-crises girl.
If she gives you an opening, there you go. If not, you can pass it off as a joke. If she asks if you'd like her to be... the correct answer would be "yes".
If you don't know the term "anti-crises girl", it's from the song that Svetlana Loboda did for Eurovision last year.
You'd be kind of asking if she's gonna save you and make your world all better.
Lucky for you, the song is in English. Svetlana is from Ukraine.
The song is here:
