Six years ago I created a drupal page pro bono for an organization I'm in. Was my first site really, was hacky af, in retrospect, I created an unmaintainable monster. And as it usually happens, I moved away, the site stops being properly maintained, opening admin view just cries "please update me" (or was it "kill"? Not sure here). Now I'm back in town and get a call from the current one in charge requesting a training. I thought this evil dark dev history of mine is now finally returning to hunt me forever. But no, she actually understood it, and after half an hour she was perfectly capable of maintaining the site. I'm stunned.
