A lonely bird,just like me?

I was attracted by the sound of a bird in a tree when walking around this afternoon.

A Lonely bird ? Maybe she was looking for another bird ? Maybe she was hurt ,or hungry ,or she was lonely ? Sometime I feel I am just like a lonely bird , even not as good as a bird. For bird can fly with its wings ,but I do not have, birds can fly to whereas they want to , but I can not .and when I live in a city ,it is not easy for us to change to another place , I had to go to work from Monday to Friday for making a living.

Maybe the bird is lucky for she is just a bird ,not a person.
