Robot's Sad

I am a robot for 4009.

I am walking on the beach.

What's wrong with me?

Why I am so sad?

I don't know my question's answer.

But I know I only a Robot.

I can't have the love like human.

Maybe it's the question's answer.

Why in my CPU have some human?

And why I can't love them?

I go on walk,

I go on sad.

Maybe the love in the sea?

But I know I can't try it.

Where am I?

Am I still on the beach?

Maybe I in the “Sad Sea”

But maybe the sad is part of love，

Right?
