Brad Schipke explains why small annoyances trigger huge anger: you have a stress threshold, and accumulated stress pushes you past it. Step on a Lego when you're already maxed out, and you'll explode over the Lego instead of what's actually bothering you.
Why do I get so angry over little things? Well, this comes from something called your stress threshold. When your stress keeps stacking and stacking up, you pass this threshold and reach this breaking point. So when you do something small, like step on a Lego, you just explode, not because you're broken, but because your stress level is maxed out beyond what most people ever have to deal with.
