the shadow and echo

shadow can be seen laying on the floor, untouchable, unattainable, unreachable;
echo due to reflection of sound waves, cant be heard, invisible, unpredictable;
she is staring at her shadow;
he is waiting for his echo;
give up, please give up and release it,
holding tightly or waiting for either will only devastate yourselves,
continue with your own life,
ignorance and cruelness is the main key to retain the living soul in your bodies.
nothing will disappear, but everything can be enclosed and blocked.
