Same Difference

I ran into an old photo of atppp today. It was an old photo taken in 1992, the era when every pupil wore a red scarf and simple clothes. At a first glance it looked exactly the same as my elementary school picture, which stunned me because I don't know him in person. Even after staring it for a while, I still can't escape the feeling of similarity. I see a resemblance to my own childhood buddies on many faces, though I cannot match any of them to a known person. Do all old pictures carry a taste of elapsed time more than their actual content?
