That’s what people do, they either make you happy, or they disappoint you.
And whoever they are - despite their merits and their faults - you live your life learning to love them.
Because in the full minute before you close your eyes and drift off to bed, you realize that these people are meaningful - that they deserve the compassion very few people can offer; but that more than that, you realize you’re a person, too. And inasmuch as they can hurt you, so can you hurt them, inasmuch as they make you happy, so do you bring them joy.
