Never Go Back?

A friend of mine told me recently that you can never go back. I thought about all the possibilities or the missing ones since you are, in a way, limiting yourself. Basically, I’m trying to understand what never going back or not really means. What the connotations are. Backwards bound seems always to fall in the negative and here I’ve done it 100 times. I told my friend that change, growth, and maturity makes revisiting what’s back there a completely different experience. But still, I had a hard time pleading my case. Maybe I was unsure it could be a good experience. I know I’ve changed, grown, matured, actively. Of course, when those changes are physical, I’m actively trying to halt the process, thank you very much strand-of-gray-hair. Anyway, I want to change (for the better presumably). Others do, too. So not everyone gets stuck and the journey can be positively grand. I guess my friend's point, because the comment was really about something specific, was to move forward and recognize that if the past doesn’t work, you can’t go back and even if it did work, you can’t go back... unless... What I say now is I go back because it IS there sometimes. I see it there waiting to be plucked and prodded. Waiting to be written about and painted. Waiting to be serenaded. To be loved. And sometimes it just fades like Hiroshima.
