You're worried about the wrong things. Fires, car crashes, the freak accident that ends up on the news — those happen, sure, but rarely, and they warn you first. Smoke before flame. The crack before the collapse. What you should actually be watching for doesn't announce itself at all. It comes from people, and it comes disguised as ordinary contact.
I don't say that to make you paranoid. I say it because I've watched you extend trust to a face the way you'd extend trust to weather — assuming good intent because nothing looked wrong. But a face isn't a character reference. Some people only hurt you when they're cornered, like animals — hunger, fear, no malice in it, and once they've passed you by, they're done. Other people don't need a reason. Damage is just something they enjoy producing, and they're patient about producing it slowly enough that you don't notice until you're already cut.
Nothing gives more consistent injury than people do, and nothing conceals itself better while doing it.
So here's what I actually think you should do about it — not withdraw, not go cold, just get honest about the trade. Try not to be the source of harm yourself, if only because it's the one thing you can fully control, and it tends to be reciprocal in the long run even when it isn't immediate. Be glad with people when they're glad. Sit with them when it's bad. Know what to say and — just as important — know what to hold back. None of this guarantees you won't get hurt. Nobody's offering that guarantee. But it buys you something almost as valuable: you won't be the kind of person who adds to the damage, and you'll get better at spotting it before it lands.
And if you ever do build something like wisdom out of this — a clearer eye, a steadier read on people — don't wear it like a badge. I've seen that go wrong more than I've seen it go right. The people who parade their insight tend to collect enemies faster than they collect anything useful. Let whatever you learn quietly correct your own faults before it starts correcting everyone else's. You can be sharp without being someone people brace themselves against.
Watching your back so you don't have to watch it alone,
