∼ Gandul si ideea zilei:

Gandurile si starile omului sunt schimbatoare ca vantul si valurile.

Nu-i nimic daca te lasi dus de val, doar sa fii atent sa vezi unde te duce.

∼ Thought and idea of the day:

The human thoughts and moods are changeable like the wind and the waves.

Doesn`t matter if you let yourself get carried away, just be watchful to see where it goes you.
