Sameness

I came back to where I grew up 5 years ago and its familiarity keeps me centered and sane. Many things here are the same. A few minor changes have evolved but the sameness ensures. I remember where the milk machine was where I could get a quart of whole milk for 23 cents with 2 cent change. I walk by where the milk machine stood every day on my path.
The local library is almost exactly as it was over 50 years ago yet I still enter it at least once a week. Am I expecting changes to happen or is there some kind of comfort in its sameness?
Comfort ensures as I like the idea of sameness but in some ways it feels like a reoccurrence of life. Some people leave home at a young age, never to return, some come back to visit. I guess I am one of those who never really left, and that is a good thing for me.
