What do I carry?
In the nature there are 4 seasons: spring, summer, fall, winter. Each of them gives us different climate: for example, in the winter it is snowing, frosts. Respectively there will be no you in shorts and an undershirt: you will catch a cold.
Spring - life time. But sometimes snow drops out. We are dressed in jackets (if the beginning of spring), and so, in the end, it is possible to put on a windbreaker and boots.
Summer - oh summer! It is the fairy tale. Here it isn't necessary to put on so any more. It is possible plain shorts and an undershirt - and I have gone.
Autumn - the beginning of winter. Here already sharp cold snaps begin. It already to you not the fairy tale - rains, at times small snow. We put on often in jackets, in windbreakers.
Winter - cold weather. Here you won't go in shorts any more. Surely put on a jacket and a cap, and it is desirable a scarf!
