The answer is Bridge.
I say everything, I hear to others around. I'm not an animal, nor part of the human race. I will, immediately, repeat after you; But only if my tail is in place. What am I?
I do not walk nor swim but you can find me on land or sea. I am toeless, but i travel on foot and no matter how far i travel, i will never be far away from my home. What am I?
I can fly like a bird not in the sky which can always swim and always dry. I say goodbye at night and morning hi I'm part of you what am I? I follow and lead as you pass. Dress yourself in black my darkness lasts. I flee the light but without the sun. Your view of me would be gone.
