Kids are dumb as hell, it's just a fact. Even the smart ones don't know how to drive cars, balance checkbooks, or talk about politics! They are just tiny people figuring it all out, and one of their common methods for learning about the world is doing incredibly scary, dangerous stuff.
While all kids are bound to pull some confounding shenanigans, some kids are more prone towards the dumb and terrifying than others.
In a popular Reddit thread, parents shared the times they've feared their kids wouldn't make it, and adults spilled their own scary childhood escapades.
The second time my 4 year old son decided to steal a knife to remove plug covers then make sparks. The first time he zapped himself and I thought good, now he'll stop. Nope.
Edit: He's outside as we speak seeing how high into the air he can throw rocks. He's now 7.
