A string

I am an eagle with a string on my leg, linked to my family. An eagle was born to fly freely in the sky but was tied up by a string. Sounds pity? I felt that at first. Now, I realized it is the other way round.

Without the string, I might not have the strength to fly; without the string, I might not dare to move. With the string, I know I can go back to my family, no matter how bitter is the world. No matter how far I flied, No matter how tired I am, I can go back to my family, have a rest before I get the strength to move on again. .

You have the string but.... you grab it?
