I finished a batch of slides for my parents, made a DVD of them to take home with the old slides and requested that they bring up a new batch of slides to scan on their next visit, which they dutifully did. Whenever I get a new batch of slides, mostly in trays, I often don't have a single clue to the contents except for the age and style of the slide tray. So when I start scanning them, I create a folder called unknown to put that tray's digitized files into and then rename it later in the process when I know enough about it to give it a descriptive title my parents will understand.
So I put the first four slides of a new tray into the scanner and got it to working. Generally while it is working I do other desk work that needs done or surf the web, answer emails and such. When the scanner stops, I look up at the screen to see the four digitized pictures and save them into the folder I created on my computer's hard drive. This time when I looked up, I saw the faces of my cousins. Except they couldn't be because the age of the tray was older than they or I were by several years.
From the other three photos, I quickly figured out that I was actually seeing my Aunt and Uncle on their wedding day and my cousins had yet to be born. It got me to thinking about how we look so much like our ancestors but due to the generational gap, the only way we really ever see that at times is through the magic of pictures and time. Sure we sometimes have genetic triggers like a distinct color of eyes or shape of the nose, but when you compare photos 30 years apart side by side, you can see how similar people really are.
My aunt in the recently scanned photo looks exactly like my cousin. My grandmother in another photo looks almost identical to how my aunt looks like in current time. Three generations and they all look so much alike.
I'm married to a native of the Philippines and our daughters look nothing like me these days due to the heavy influence of their mother's genes. However, if you take their baby pictures and slap them up against a baby picture of me, we look like the peas in the same pod. If I had had sons, perhaps they would still look like me when I was their ages.
Its one of those things that should be intuitively obvious but it still caught me by surprise when I looked up and saw my cousins about 30 years too early.
