gravity is the answer
The things I bite, do not bleed, I do not bite until you push me; I bring my victims together each time I bite, But they will come undone if you pull it just right. What am I?
I am easy to see, but no one likes looking at me. Without me, there would be no you. I can make you complain, or make you happy. But you almost always take me for granted. What am I ??
