I wonder if this is a generational thing. I grew up before social media and have long taken the position that I never post anything to the Internet that I wouldn't want public. I don't have a secret Reddit account or anonymous Twitter profile where I post stuff that could be fired, charged or worse.
This goes moreso for work. I assume anything you do can and will be used against you. I have zero trust. You're being a sanitized version of yourself. Do people not know this?
It's part of the reason I hate these working bonding activities. Well, that and being neurodivergent. There are fiarly standard questions and I have prepared answers that may or may not be the truth. Just like with interview questions. Sorry, but none of you are my friends or can be trusted. You might be shocked how often confiding in a coworker is used against you.
The trick with coworkers is saying just enough so they think they can trust you without saying anything that might get you fired or have other consequences. You can't say nothing. That's almost worse. But you have to basically invent a persona, particularly if you're neurodivergent because the default position of neurotyhpical people is to not like you.
And at the end of the day so much of your work life is governed by whether or not people like you. And I hate it.
So for a trust exercise, I'd come up with something everybody has likely done or is at least sympathetic to. Like, nothing to do with stealing. That might get you fired. Here's an example: "when I was in high school, I lied to my parents and drove to another state for a party and got drunk with my friends".
It's better to base your sanitized answer on the truth but I'm not above wholesale lies. They're just harder to remember so you have to be light on details but not too light.
