I wasn't sure what to go as this Halloween, so I went with going as a drone because it was easy to pull out. Plus I was already going to a fetish Halloween party, so it worked out great.
It's fun to roleplay being a brainwashed drone - something part of a hivemind rather than a person. I like being able to shed the burden that comes with being a person at times, get my brain to shut down and relax a bit, and just enjoy being an object.
