Have you ever gone back to a place with which you have an emotional attachment? Maybe the house you grew up in, a favorite hang out, your elementary school....
Going back, you realize it doesn't have the same energy it did then. Often the space even feels smaller than you remember. It just isn't the same.
The energy that comes with our memories isn't about the place itself but we associate it that way. Our emotions are about the people who occupied that time and place with us. That energy has changed.
We may be able to make new connections, build new energy and create new memories in that place but we cannot get back what was in those past times.
Sad but true.
