If you’re having a bad day, lots of minor things appear major. On a good day major things can be shrugged-off as minor/petty.
I do know of some people though that will blow-up really petty things to make an issue out of them, one such person is my very own Aunt..
ex. it’s raining.. for her it’s going to be it’s pouring, don’t go out, the streets are flooded, stay at home. You’ll drown!
