Second, appreciation has to come in a form the receiver values and hears clearly. Gary Chapman makes a similar point about love in his book The 5 Love Languages. Some of us take in love through words (“I love you”), while others hear it more clearly through acts of service, quality time, physical contact, or gifts. If I feel unloved, it could be because you don’t love me—or it could be because you’re expressing it in a way that I don’t take in.3
