Have you ever gone back to a place that was home. Somewhere safe but it's changed so much no longer the same. With age so much change hard to accept. Becoming the seniority by default. The mentors; who trained you, retiring. Those regular faces replaced by new ones.
Something that was normal feels awkward now uncomfortable.
Trained in the circuit while others used family to move up. Know for my hard work while others us nepotism to advance.
There's no going back once you do. Everyone has moved on, no reason to go back. Everything that had meaning treasures by the heart no longer hold value in reality.
