An amazing children's story by Nikolai Nosov -
the Russian master story teller. One day mother goes out
of town and Mishka and Kolya are left to cook their own
food. How much porridge should they take? How much
water should they add? They have no inkling of it.
Cooking a simple meal of porridge becomes an unforget-
table experience.
