Mono no Aware
A coworker from a sister team in Builder Tools recognized me on the bus. He lamented my departure as unfortunate and inappropriate. We talked about old projects and he said in two years I could reapply and head back.
He's an SDE 3 now. He was a 1 when I left ahead of fears of being fired. His manager put him on a PIP. Hard not to wonder how things could have gone if I hadn't been under my manager then. Inflection points.
