A facet of Neuroticism
Irritability measures your threshold for frustration and anger: how easily something bothers you, and how quickly that annoyance surfaces when things don't go as expected.
You have a fine radar for the unfair and the badly done, and you don't keep quiet about it — which is sometimes exactly what was needed. The cost: small things set you off, and those nearby learn to tread carefully.
It takes a lot to get under your skin; you absorb daily friction without stockpiling tension. The risk: sometimes you swallow legitimate annoyances that were worth saying out loud.
A low threshold isn't 'a bad temper' and a high one isn't 'being a good person': they're different thermostats. Anger in time signals limits; constant anger erases them. What matters is whether your irritation points at something that genuinely needs changing.
Where it shows. It shows in traffic, in queues, in how you react when someone's late, and in whether someone else's bad day rubs off on you or slides right off.
