I have definitely been the only one in the room to realize that the person everybody likes, is a snake.
Were I the first and only person in ghe world to realize this? No, definitely not. But in that particular constellation of people in one specific room at one specific time, I was and it fucking sucked everytime it happened.
There have also been plenty of times where I was the one to figure out late that someone was shitty because I kept believing in the best of them, and that also sucks.
Can't judge people who don't catch on early to someone being a shit person.
