This is very rational, and yet I have lost track of the number of computers I ended up with when I left companies, including this lovely machine I was gifted.

Twice, I tried to give back the computers I had, contacting the supposedly-interested people a couple of times, and no one got back to me. The first time, I lived in fear for a few months that someone would catch me, but now I follow whatever instructions I am given, and I just don't worry.

Yes, it seems wildly irrational to me too. Yes, I do work at a lot of startups, how did you guess?
