I have a face but never smile, I travel with you mile by mile. I have two hands but cannot clap, and never need to take a nap. I chase the seconds all day long, yet never sing a ticking song. I help you hurry, help you wait, and tell you when you're running late. I hang on walls or hug your wrist, and without me, plans might be missed. Though I grow older every day, I never age in quite your way. What am I, keeping every moment in its place?
