Answer:
I cover what's real; hide what is true, but sometimes bring out the courage in you. What am I?
Every dawn begins with me. At dusk I'll be the first you see and daybreak couldn't come without. What midday centers all about. Daises grow from me I'm told. And when I come I end all code but in the sun I won't be found. Yet still each day I'll be around.
I go up and never come down no matter how hard you wish. As I get higher more wrinkles crawl onto your face.
I am full of holes but still holds water.
I am the kind of food monkey likes and people slip on me and fall in cartoons.
Whoever made me don't want me. Whoever bought me don't need me. Whoever use me don't know me.
