Answer:
When I live I cry if you don't kill me I'll die.
I can be long or short. I can be grown or bought. I can be painted or left bare. My tip can be round or square. (one word)
I think you live beneath a roof that is upheld by me; I think you seldom walk abroad but my fair form you see; I close you in on every side you very dwelling pave and probably I'll go with you At last into the grave.
I am black and white and full of fuzz
I ask no questions but receive a lot of answers
Whoever made me don't want me. Whoever bought me don't need me. Whoever use me don't know me.
