Ive become Mr Smith

Similar story here too.
My 'ex' and I moved into a brand new house November of 1972. We were the youngest couple on our 7-house cul-de-sac. Our kids came later.
Here I am 50 years later and still in the same home. I have one neighbor who is still an original owner, his wife passed several years ago. Both of us have watched our respective kids grow up and move on.
The other five houses have all sold multiple times as other families have moved in, kids grown, and move on.
Circle of life indeed.
Where did the time go?
