And of course, everything was made of clouds, not some kind of strange plastic. You had to climb them like a rock face.
And you didn't need to attach a safety harness because if you fall into the clouds, they're so soft that you can't get hurt or injured from such a fall... you just float down like through cotton wool, gradually decreasing your speed.
Знание некоторых закономерностей освобождает от изучения многих фактов.
Мечты сбываются рано или поздно, так или иначе.
