Winter
This is, obviously, entirely subjective, but I would find it very difficult not to have a proper winter during the year. On the days like the ones a that happned quite a few times over the last couple of weeks — when a light frost is biting your nose and cheecks and a magical feather-light snow is falling all around....
The air is crisp and sweet — can an air on some sunny beach ever smell like that? If you let the temperature to fall a few more degrees, then snow itself would become crunchy, start squeaking under your feet. Can sand behave like that? I did not think so.
Of course, there are bad and ugly parts of winter as well — like when it is snowing slit, or that same snow that was so clean and pure just a few days ago starts to melt, turning into a terrible mess... But I still am pretty sure that even a couple of weeks of real winter are worth that.
Now, the problem is that there has not been a single real winter in my homeland for the past 10-15 years. And all the joy of real thing this year comes from Prague...
