One of my best mates is someone who I've worked with, at a few jobs, over the past 30 years. We met in our first ever technical support job then, over the following decades, kinda landed at the same places around the same time. At one point, I even hired him as a contractor into a team I was building.

We've helped each other move houses, we've been there for each other's weddings, and our kids have pretty much grown up together. We get together for pub meals and barbecues as often as we can - sometimes just he and I, sometimes with the wives and kids.

My point is, over those 30 or so years, we've discussed a lot about our respective histories, families, school mates, hobbies, etc. There's probably not much we haven't shared about our lives with each other.

Literally two weeks ago, he randomly sends me a picture of the back of a family photograph that was taken when he was a little kid. Had the name of the photographer and the photographer's phone number stamped on it.

Turns out my grandfather (a professional photog at one stage in his life) had been my mate's family's photographer all those years ago. Used to visit them once a year to take all the family photos. My mate remembers him quite well - just funny that we never connected the dots before now.
