I still remember an off-site team building event that I (luckily) skipped the first half of, where our tech lead tried to speed-run some intimacy building by going around and asking what everyone's biggest fear was.

I had just recently become a parent, and if you're a parent reading this, I'm pretty sure that we both have the exact same biggest fear in our lives - and it was absolutely not one I was willing to fucking share, even with those coworkers that I felt close to.
