Do you know why I always walk behind you always?
Because walking behind you, make me see all the action of all of you.
If I walk beside you, I can see but not everyone.
If I walk ahead of you, I can't see.
The walk behind you I can help you when you fall down.
Even if I don"t see your face. But I can tell that you happy or sad from the tone of your voice.
I will walk behind you. If you have no one. you will have me at the walk behind you all the time.
