It frustrated her to no end, she never could quite understand how it was I was able to sit in a couch and stare blankly in front of me without doing anything or moving. Worse, that I seemed to need it, and then complained about not having enough time to finish whatever I was supposed to do in the first place. It drove her bonkers that I was able to study only under great pressure, when I should've been in bed already, and do so little. She never did quite know if she should be happy or annoyed that I passed every damned time
