ya i notice usually late nights, girls will mostly sit behind, cos they scared bah...
i also notice that most cabin crew after overnight flight will sit behind to stone or zzz... even when my back seat is filled with their luggage (my boot is small) & my niece's soft toys, some will die die cramped in the back seat..
but can understand lah, redeye flight, not enuff slp, so want to hide behind to stone..
I hitched 1 Sq to home before.. Morning ride.she sleep until the head bang my window... Ke shag.
