Vicky’s father wanted him to become an active boy. So, he bought him a trick robot. Vicky did not know that it was a trick robot. He was glad to have a robot to do all his work.

Vicky, I have bought you a robot. This intelligent robot will do all your work. Enjoy!

Vicky is excited to test his new robot.

I am hungry. Cook some salad for me.

I do not eat salad. So, I cannot make the salad.

Do you want me to strain my back? I cannot do that.

What? You are a robot. You cannot refuse me. Clean my room now!

Really? I cannot believe this! At least, charge my phone.

Why don’t you do that yourself? I must make some calls.

Aah! I have a headache now. Get me a cup of hot tea.

My battery is draining by listening to you. First, you charge my battery.

I am tired of you! Play me a pleasant song. I want to relax.

That’s a great idea! Why don’t you play me one?

Oh no! Dad! Please sell this robot. It is totally useless.

Yes. This time please sell me to an active master. I don’t want to work for lazy people.

Really? Is that why you did not help me?

No more robots for me ! I will do all the work myself.
