Maybe I am a dumb

But I can't be silent

Until I decide to be unexpressive

Maybe I am a tortoise

But I can't be slaughtered

Until you flip me upside-down

Maybe I am slower than rabbit

But you can't defeat me

Until I give up my perseverance

Maybe I am old as vine

But I am wise enough to manipulate

Until I am running out of hope

Maybe I am an amphibian

But you can't survive without land

Until you evolve to live in  Arctic and Andartic

Maybe I have five senses only

But I am an instinctive person

Until I live in this green and blue globe
