Overheard on the subway

The winter has come and the snow is falling. I am on my way to work and get off the subway in Old Town. I walk behind a little boy, maybe 3 years old, who is dressed in a thick overall, boots and mittens and the whole lot. He holds on tight to his father´s hand and talks talks talks...

Boy: Daddy, it is snowing and the snow comes down the chimney
Father (looking like he has not had coffee): Uhuh
B: What if you are cooking and the snow comes down the chimney, then the snow will come into the food
F: Mmmhhmmm
B: But what to do if the snow comes down the chimney and you are cooking
F (looks desperate, thinking hard on what solution to present to this snow-in-the-food problem): Ahem???
B: Snow in the fooooood. What to do? What to do? When it comes down the chimney.

An so on.
