Why I Have Four Legs? ?

I would like to put it back, Before uprooted and smelled, arranging with my legs, not look too appropriate, as there is no coordination, to call these as hands. When I tried to push it, It gets ripped and torn, When I try very hard to put it back, Where it belongs, Before it was smelled and scavenged, To keep this place neat. I couldn’t, as I have four legs, Not two hands and two legs, Those who have the hands, Can do it with ease, Not resort to bite and pick. Those who have the hands, Can work hard, using the digits and pulleys, To make this world clean and wonderful, Not keeping their hands as legs, To kick to mess to live in trouble..
