Neexistuje, aby

That is an expression in Czech that amuses me. Even though existovat, as it probably shows, means to exist, neexistuje, aby means that something never happens, is not true, as in: Neexistuje, aby přišel pozdě - literally: It doesn't exist that he is late, that is, It is out of the question that he will be late/He is never late/He is not prone to being late.
