To care for someone can mean to adore them, feed them, tend their wounds. But care can also signify sorrow, as in 'bowed down by cares. ' Or anxiety, as in 'Careful!' Or investment in an outcome, as in 'Who cares?' The word love has no such range of meaning: It's pure acceptance.
Part of being human is that we can’t go back, we can only hope that if we come across that moment again we’ll do it the right way.
