“Sisters by blood, friends by choice,” is a lovely sentiment, but let’s be real: It took a while to build that friendship. You fought with her over boys, stole clothes from each other’s closets and battled over who got to sit in the front seat. Now that you’re older (and wiser), it’s time to show her how much you really care. Pick up one of these genius gifts (and try to wait at least a week before you borrow it).
