I have a short fuse when people either A-argue with me on something that I absolutely without a doubt know that I am right about or B-something in which CLEARLY they themselves have no understanding of.

An overweight person giving me advice on dieting- fuse blown.
An out of shape person giving me advice on working out- fuse blown.
A non military affiliated person giving me advice on a military affiliated issue- fuse blown.

Luckily in my mid thirties my fuse blowing is all internalized so I don’t turn into cra cra Ayme but I might throw death eye daggers.
I am not always right except when I am. There are certain things in my knowledge base that are there either through something I learned in school or something that I have seen with my own eyes. I have tried to distance myself from these know-it-alls just to stumble into a relationship with another. I think that I am going to introduce all my know-it-all acquaintances to each other, throw in a random comment and sit back and watch. That at least would give me some entertainment!
