Congratualations on your girlfriend!

Heidi Hey yo John. Lot's of congratualations on your girlfriend!
John Yes, thank's a lot. Very sweet of you. But to be honest: I still find it weird.
Heidi Weird?
John Yes, that Dutch people always congratulate everyone when someone is having birthday.
Heidi Don't they do that in your country?
John No, of course not. We congratualate only the one who's having birthday.
Heidi Yes, well, know that you mention it. It's quite weird indeed.
John But you know what I like? Those flowers!
Heidi What do you mean?
John Well, look, if you want to give someone something and you can't think of something, you just give a bunch of flowers.
Heidi That quite convenient indeed. But tell me, what else do you find strange about Dutch people?
John Oh, I could write a book on that. On how you eat fries, on your bicycles, on your political parties, your toilets, your tolerance...
Heidi Well, I don't know if we're that tolerant. I have to admit that it often looks like we are, but perhaps it's really just indifference.
John Do you think so?
Heidi It doesn't interest us what someone believes, what someone's sexual preference is, what someone smokes or drinks as long as someone pays.
John And do you know the most interesting thing about Dutch people?
Heidi Well?
John Their self-critisism
