With whom is he playing ?

 I asked this question to Anirudh.

Question is like this. 

In a room, there are 4 boys. 

1st boy is doing drawing. 

2nd boy is playing chess. 

3rd boy is in the kitchen cooking. 

What is 4th boy doing????

Listening to the question, Anirudh started giving me the list of 

possible works 4th boy would be doing. 

But I said wrong answer to every reply he was giving. 

Getting frustrated, his face was turning red. I thought it is the time 

to tell the correct answer. 

I said 2nd boy is playing chess. Its a normal chessboard game. 

The game requires 2 players to play. One is the 2nd boy and the 

other one is the 4th boy  !!!
