All for a gun

It was 9pm - time for the older brother to sleep. But he and little guy were fighting over the iPad for the Nth time. And this was after fighting N times over M other items.
Mom had been screaming at the older brother to go to bed. But neither was listening.

So, Dad found the need to finally step in.
"Nishu, go to bed!"
"But papa ..he .. "  he started
"I won't tell you again. I want you to go to bed right now and stay there" Dad said and turned away - not wanting to squabble about more life-and-death issues between a 9 year old and a 3 year old.

So, the older brother walks into the bedroom and gets onto his bed. He then realizes a crucial fact. His toy gun - the one which makes crazy noises and lights up like a christmas tree - was out there in the living room. He realizes that in his little brother's hands those fresh batteries would go dead before the little head hit the pillow for the night.
He calls out - not wanting to violate his dad's orders by coming out -  "Nischal! Can you bring my gun here?"

Nischal notices the gun. And picks it up with a smile.

'Nischal! Can you bring me my gun? Pleeease'  goes the brother.

"What did you say?" asks Nischal innocently.
"I said, can you bring my gun here?" says Nishu even more loudly.

Now - everybody in the apartment - in the far rooms were hearing this conversation. Only Nischal - practically standing outside his brother's room - was apparently not.  

"Sorry annaa ( older brother), I can't hear you" continues Nischal.

This continued for a couple more times before Nishu realized he was being played.
