From the introduction:
This isn’t one of your best days. You came unwillingly, leaving unsolved issues at home, and bad traffic pumped even more adrenaline into your bloodstream, now you’re frowning. The place is packed, and while you contemplate the big mistake you made by coming, you spot an acquaintance. He sees you too, and here he comes! No, not that pedantic dork! Too late to pretend you haven’t seen him, you force yourself to smile as you greet, politely. He doesn’t respond. Instead, he gives the biggest, longest and most sudden hug.
"Easy! Don’t get me wrong, it’s just a game", is his smiling response to your questioning look. "And I think you’re gonna like it! Here, take this card. It’s yours now." You inspect the small card. Your eyes glitter.
