This is a no-judgement, non-LTB question as I'm just curious. My own DH pitches loud hissy fits (I think you'd all say throwing a strop/toys out the pram). He's not doing it at us, he's doing it to and at himself or an inanimate or lost object. In other words, very annoying but not 'dangerous', iyswim. I tend to be a quiet 'fumer/mutterer' in the same situation. He thinks he's in the majority of people, I think I am.
So 'fess up. Which kind of person are you/your partner? Do you fume quietly at those lost keys/broken doorknob or do you curse it to high heaven?
