“Don’t judge a book by its cover” is one of the first life lessons we learn as children. For the most part, it’s about looking past seemingly unappealing superficial traits to know the real person beneath them.
The saying can also work the other way around. Sometimes, we need to be wary of the overly pleasant person who may actually be hiding something sinister from within.
This was a topic of discussion in a recent Threads post, where people discussed the telltale signs of a covertly dangerous person masking themselves behind niceness. If you have trouble reading people, you may learn a thing or two just by scrolling through.

One of the biggest giveaways is when their kindness is conditional. They seem generous and respectful only as long as they get admiration, attention, or obedience. The moment they’re told “no,” criticized, or rejected, they become manipulative, guilt-tripping, angry, or quietly vindictive. Genuine kindness doesn’t disappear when expectations aren’t met

I think one of the biggest tells is whether their kindness can survive a loss of control. I’ve seen people that seem extraordinarily nice as long as everyone around them is behaving in ways that keep them comfortable. You can learn a lot by watching who they become when they don’t get to control the outcome.
