The only person I recognize as ISTP is my dad.
He's awesome. Every time I broke something in the house, he always manages to restore it to acceptable state , assuming said object is not destroyed beyond recognition. I love his random funny observations and how he usually uses sarcasm to get us to eat.
What annoy me about him
The first thing that comes to my head is that he watches something, he keeps calling me and my brother into watching scenes of somebody or animal getting killed, even though I clearly stated those things scare the shit out of me.
Also, his constant reminder that as a girl, I need to cook and help out with chores more. I wouldn't mind it if he just tells me that I should help out being part of the family, instead of bringing out the gender roles.
And I can't think of anymore right now.
EDIT; I don't think I hate ISTP. The ones I see on the internet seem pretty cool. And I have some annoyances with my dad, but nothing big. ISTPs are chilled people.
