I remember when I lived in Bahrain (which was not as 'developed' then as it is today) two girls in my school were freaking out about wearing the same skirt. It was stupidly ridiculous at the time because Bahrain only had like one shopping centre by that point and a couple of shops so everybody was wearing the same freaking thing. They stood at opposite ends of the corridor and would squeal when ever they looked at each other. It was just funny for the rest of us. Good times.
