At the top of your lungs you could scream use all your force, explode with "I love you" But if you silently brushed the hair from my face, breathing softly as you did It would be so much clearer. He loves me. He loves me. He loves me.
Holding hands is noiseless. Nothing but the pulse between our fingers beating in unison. Silent to all but the minuscule space that exists between our flesh. And still it makes a bigger sound than your melodic laugh of "you're perfect."
If you want to make me feel loved, show it. Words are too easily lost. Noise pollution.
