If you love something, set it free. If it comes back, it was, and always will be yours. If it never returns, it was never yours to begin with. If it just sits in your room, messes up your stuff, eats your food, uses your phone, takes your money, and never behaves as if you actually set it free in the first place, you either married it or gave birth to it.
I didn't write it, but gee... I dunno.
