Everyone happened to find her/himself in a situation when the only thing left to do was just to exclaim in a temper: “Would you believe in that, what a bad luck! The bus, which runs once per hour, is leaving from under our very nose; in the store just before us someone buys the last thing, which is as necessary for us as the air we breathe; boss walks into the office right at the moment when we describe in bright all his shortcomings…From time to time something similar happens to all people, without the exception. If one “bad luck” follows another we usually speak about “a run of bad luck”, but we have a firm belief: unlucky period sooner or later will change into the lucky one, we just need to be patient and wait for this moment.
