Doesn’t Fly Even With Wings
I have four wings but cannot fly,
I’ve never laughed nor will ever cry,
As much as I’d love to leave the ground,
I toil away with nary a sound.
What am I?

A windmill. The typical windmill, like the ones Don Quixote chased, have four vanes or sails. You might even say they look like wings. Windmills don’t have emotions, so they can’t laugh or cry. And since they don’t have actual wings, windmills don’t get off the ground. A well-oiled little bugger won’t make a peep.
Soft and Transparent
I am soft and transparent.
I am so small that I can sit on your finger.
I have no light but I help you to see the beautiful world.
What am I?
A contact lens.
A Creature, Part Man
This creature, part man and part tree,
hates the termite as much as the flea.
His tracks do not match,
and his limbs may detach,
but he’s not a strange creature to see.
What is it?
A man with a wooden leg.
Crawl on the Earth, Rise on Pillar
I crawl on the earth and rise on a pillar.
What am I?
A shadow.
What Work is Never Finished?
What work can one never finish?
An autobiography. Unless you’re writing it in your death bed I suppose, but even then, how will you be able to record the time of death?
Everybody Does At The Same Time
What is it that everybody does at the same time?
Grow older.
