Most people would agree that they do not stay the same. As all live and circumstance in which we live are in a constant state of change (whether we are highly aware of it or not), meeting people at one point in time, may be entirely different to meeting them at another.
I had an experience where this happened last year. I met someone rather serendipitously , almost four years after I first met them. Not only had they changed (particularly their appearance), so had their circumstances. So had I changed, in both these ways too.
The first meeting was at a party, with the theme of black and white. He was dress as a pirate, and I looked like I was meant for a American marching band.
The point of our connexion that night was not drinking. He had just given up for good, and I was on a self-imposed twelve-week hiatus.
We sat on the floor in a room away from the main party for a while. I don't remember what we talked about, but I remember being impressed. I also remember wishing that he was not already seeing a distant friend.
The Second connexion came through university. We ended up in the same class. At first, I didn't release it was the same person. He was not a pirate. He did not have a septum piercing anymore. He had just shaved his head. Our original proclivity for conversation still existed, despite the time and the changes, yet it was if I was meeting someone entirely new.
