“I was trying to feel some kind of good-bye. I mean I’ve left schools and places I didn’t even know I was leaving them. I hate that. I don’t care if it’s a sad good-bye or a bad good-bye, but when I leave a place I like to know I’m leaving it. If you don’t you feel even worse.”
― J.D. Salinger, The Catcher in the Rye
