Answer:
You use a knife to slice my head but you weep beside me when I am dead
In spring, I am gay in handsome array. In summer, more clothing I wear. When colder it grows, I fling off my clothes. In winter, quite naked appear. What am I?
I have a head and a tail but my eyes can never see my tail.
The more it dries the wetter it gets. What is it?
I am good at concealing what's real and hide what's true. Sometimes I bring out the courage in you!
Whoever made me don't want me. Whoever bought me don't need me. Whoever use me don't know me.
