It is the end of the day. They are all tired.
Sir wants to make sure all 36 children are safely back in the bus.
This time, Didu wants to count.
She notices that each row in the bus has four seats.
So she counts loudly in fours.

“4, 8, 12, 16, 20, 24, 28, 32… ”
She stops just before saying ’36’.

“Sir, two kids seem to be missing and are not in the bus!” she gasps.

The bus driver, Didu and Sir count the sleeping class again.
Who could be missing?

“Aaaah! Come, see… here is one missing fellow,” the driver says from the back of the bus.
On the last row is Montu, fast asleep and snoring!
