Pain

Pain is sneaky, ruthless, humbling.
It waits until just the right time to strike--when you are in the shower, getting out of bed, eating, talking, stretching, dressing. It senses your fear and takes full advantage.
Describing it brings grimaces from those you love, so you clam up and suffer. And wait for tomorrow, hoping pain is bored and attacks someone else.
Giving in to pain is not humiliating. it makes akk the sense in the world. Pain is telling you that you were having too much fun.
