Why do weeping willows weep?

Question

Why do weeping willows weep?

Answer 1

If you mean "cry"... they don't.

Answer 2

They are sad and mournful trees.  They stand rejected and detached from the world.  They weep because they are alone.  They can not run and hide, so they hide their heart behind bowed heads and hidden leaves.  That is why they weep.

Answer 3

Because the tree to one side is an ash, the one on the other is a beech and neither will leaf them alone?

Answer 4

That is merely the name, the trees do not actually cry. Sometimes the long swaying branches in the wind may make the tree look like its crying.
