If you walk into a meeting and it isn’t clear who the owner

If you walk into a meeting and it isn’t clear who the owner is, feel free to leave and go do something more valuable for the company.

“More valuable” is questionable here. Sure, if you have other priorities, go and work on them and don’t let me (or the meeting owner) waste anymore of your time. If there’s anything important that involves you, I’ll likely send you an email about it later.

I’ve been getting into radical candor lately and I think this is a good example of when being candid helps both parties.
