The definition of irrational (according to The Free Dictionary):
- Not endowed with reason
- Affected by loss of usual or normal mental clarity; incoherent, as from shock
- Marked by a lack of accord with reason or sound judgment: an irrational dislike
Well I’d like to add one more:
- Something that makes sense if you really think about it
I’ve made it known before that I have a fair amount of rational fears, but would you believe me if I told you I also have some that would be regarded as irrational?
My complaint about the definition is this:
If any of my irrational fears ever happened, they wouldn’t be irrational anymore; I’m afraid of that happening, thus rendering my fears rational. Right?
FEAR #1 – That I’ll drive off with the gas pump still in my car.
I leave my engine running, so anything's possible. Including a fire.
FEAR #2 – That I’ll drop my keys in a sewer grate as I walk over it.
Keys please state in my pocket!
FEAR #3 – That I’ll jump over the ledge of a building if I’m on the roof.
Yeah... this one's just crazy...

I was pumping gas for my mom once on our way somewhere years ago and she drove away with the pump attached. Insane!
See! Not irrational!
it was a moment of sheer panic and “What the fuck do we do now?”.
Well what did you do?
Laughed asses off, stopped at another gas station, removed it and placed it next to a pump in the back. Didn’t want to just throw it away since it was, you know, filled with gas. Ridiculous.
I have that third fear, too.
I wonder if it’s innately human. And what does “innate” mean?
