"Coincidence" (náhoda, zhoda náhod). In Genesis, the first book of the Old Testament in the Bible, after God created the earth he made Adam and Eva and let them live in the Garden of Eden, but he told them not to eat the fruit from the Tree of Knowledge (or Awareness), which happened to look like apples. But then Eva couldn't resist the temptation of the attractions of knowledge, and she took a bite of an apple, and then persuded Adam to eat some as well. Then God punished them by banishing them from Eden, and they had to go and live in the wilderness which lay to the east, and they were not happy any more.

Now consider this coincidence: Mr. Sinay gives an Apple of Knowledge to Mr. Lohr, and a bouquet of flowers to Ms. Molnárová, whose first name is Eva. You couldn't make it up… But the word coincidence itself means that there is no significance in a combination of events, and that's why it's tricky.
