Thought I would share this because it is hilariously illustrative of ISTPs.
Went to a concert for my most favorite band ever and came back wired, hyperactive out of my mind, jumping all around the apartment, and was trying to explain what it was like to my ISTP friend:
Me: "it was like...when you go to see that band!!!
Me, thinking I just got the band wrong and trying to name another of her favorites: "ok ok ok it was like when you go see THAT band!!!"
Her: "It was like if someone put a HUGE pile of cheeseburgers in front of me!!!"
