what do u think?? how it might be
Well, sorry to be pessimestic, but a lot of the older Polish folks aren't really used to seeing their kids, especially daughters, marry outside of their race and religion. I don't know who this girl is, and what her family is like, but I would be prepared if I were you, to recieve some hostility at first. If you are a good guy, eventually that will pass and you will be accepted. Hell, you might be lucky, and hit some liberal family that really doesn't care about ethnicity/religion etc...
Go meet her parents with an open mind, and be prepared for the worst. If you find it hard to communicate, and find some similar views with her family, then just take the girl aside and ask her about their personalities, about what they like etc.. get some gifts for them. I'm not saying to buy their love, but be very kind and honest, and I don't see why they wouldn't like you.
What religion do you practice, if you don't mind my asking?
Turks, Greeks the same as Arabs? Yes, go on living and thinking that, little Polish friend.
That would be like me saying that Poles and Germans are the same thing. Would you enjoy having that comparison?
