If the thing also includes person, it'd be my hubby :-). If it's just an inanimate object, it'd be a knife.
If you fall in love with a book or movie, do you tend to watch/read it again and again? If so, what's your upper limit on repeats?
If its a book, there's no limit to the number of times i'll reread it. One of my favourite books is "Lord of The Rings" and since i first read it, i've reread it easily 30 times. And, i know for sure, i'll read it again sometime in the future. As for movies, 5 times would be my cap.
