My condolences to the family and friends of Alice from The Brady Brunch. She passed away today after suffering a fall. You will be missed.
The quickest method of differentiating ISTJs and INTJs is simply to ask if they like Monty Python skits. ISTJs detest that juvenile nonsense while INTJs will perk up immediately and start reciting lines.
I hate that feeling of being tired enough to go to bed but not quite tired enough to fall asleep. I read the book I'd borrowed from the library to help the process along and sure enough I got that I'm-tired-enough-to-sleep-now feeling. But I had only 20 pages left.
I know how the book ends but I pushed right through that I'm-tired-enough-to-fall-asleep phase to find out, and now I'm back into I'm-tired-but-not-that-tired.
