Some are and some aren't, Arien. You can't get away from that fact.
How about, a few who are and most really aren't in this case? Anyway, I'm sure you get the idea..
As it happens I am not really supposed to change their work hours regularly anyway, I was just doing it because they needed that help and I was able to. I can still do it but now, as of this week, I choose not to. Of course though, any new Pole joining will still be treated with kindness until they decide to turn on me too.
Has it ever occurred to you that maybe, in some situations, you could point the finger at yourself, instead of punishing others for your own misfortune?
I fell in love with a Polish colleague so deeply that I took it upon myself to learn the language, albeit I am not fluent but can have conversations. However I never did anything wrong, we remained very close friends.
Well, it turns out that she has a boyfriend, or a husband already. (Which is it?) Too bad for you.
Then one day she just decided I was nothing when her boyfriend gave her hassle because she is not allowed to have male friends.
That's what you tell yourself. Ofcourse the guy doesn't like you. She's his girlfriend, and you've said it yourself, you've allowed yourself to fall in love with her. (And maybe she even encouraged you in some way, I guess we'll never know!) The bottom line? There are more than enough ladies out there who don't have a boyfriend, or a husband. (Should I draw you a map?)
Regardless, you shouldn't take it out on others, and not even on her, simply because you're disappointed. Hey, don't expect everyone to like you, and don't expect everyone to please you either! There's no point in debating this really, and no actual harm has been done? (Okay, maybe she has bruised your ego a little, but you should be able to shrug it off!) You'll be fine.
