What has a coat? Hugs you not in sympathy? Whose smile you'd rather not see? Whose stance is a terrible thing to see? Who is it that brave men run away from? Whose fingers are clawed? Whose sleep lasts for months? And who's company we shunt?
I never sleep yet sometimes I weep. I can get angry or just be happy. Wherever you go, I will follow. No matter what you do, I will be there. I cannot die. What am I?
