Creature

I am a creature,

Who walks in the morning, i.e. Childhood with four legs,

Walks in the noontime, i.e. Young age with two legs

Walks in the evening, i.e. an Old age with three legs,

We would have spent our entire life,

But we still don't recognize ourselves.

My parents gave me my name,

They taught me to speak,

Perhaps I am the shadow of my parents.
