faces to backs

Two photos with astonishing meanings: Girls are sitting with their back to what is happening behind them. Boys are looking straight forward, even smiling a bit!

I am not sure why the girls are turning their backs: are they not willing to be identified? Ya, most probably; I think they left their houses claiming to their parents that they were going to study with each other in one of the girl's houses and took the opportunity to escape and have some fresh air on the Corniche.

The boys, just leave without any explanation to their parents and meet, making plans, sitting on the same seaside. Both parties have no money to meet in cafés. Even if the girls had some money, they would not dare to go to café houses.
