When I was in high school I had a close-knit group of friends. We spent just about every weekend together.
At night we used to talk long walks along the lonely roads of the rural community where I grew up.
When cars would pass us, we'd stop on the side of the road and assume a 'family portrait' pose - we'd stand side by side, facing the road, turned slightly inward towards those in the center of the group, those in front kneeling, those in back with a hand placed lovingly on the shoulder of the person in front of them, all smiling inanely and vacant-eyed at an imaginary photographer in the distance.
We'd hold the pose until the car had passed and disappeared into the distance, then w'd resume our walk. When the next car came along, we'd form our family portrait post again. And when that got dull, we got creative.
We'd form a still-image of a Kung-Fu battle.
Or a still-image of a dance-routine, usually Lord of the Dance style.
Sure, we were weird. But we did have fun.
