20+ years ago, when he was 18, he was arrested for the afternoon because of a student protest.
So now on the visa forms, when entering Australia on vacation, he was asked if he had ever been arrested.
He checked yes. The border control people in Australia denied him entry, and put him on the next plane back home.
When he told the border guy the full situation, the border guy said, "Next time, just check NO."
Then, this interesting quote: "You give us the papers we want. We give you the papers you want."
Meaning: make the papers (visa forms) look the way we want them to look, and we'll give you the papers (tourist visa) you want.
I remember that rule of thumb when crossing borders, or filling out paperwork to open a new bank account in a foreign country. Luckily, I've never had to lie, but it sure helps to make the forms look the way they want them to look, instead of treating them as an opportunity to express your individual quirks.
