Bad vibes, definitely. But I can tell you about related "friendly" bad vibes. My parents lived in Cuba in the late 40's -early 50's. They used to see Papa a lot at one of the local bistros. My mother finaly decided to bother him and got him to autograph her first edition of OLD MAN & THE SEA. Years later, back in the states she lent the book to one of her friends, who never returned it.
