The wonderful sound of pebbles sliding under their feet was intertwined with the singing, which was full of poetry; They held each other's arms tightly, bent down and threw their long hair to the front, sang and marched until the tip of their hair touched the ground, then bent their knees slightly, raised their heads hard, threw their hair up so that it was instantly perpendicular to their bodies, and then let it hang freely behind them, so that they shook their hair and danced until they had a good time.
