The sun did not shine.

It was too wet to play.
So we sat in the house
All that cold, cold, wet day.

Too wet to go out
And too cold to play ball.
So we sat in the house.
We did nothting at all.

So all we could do was to
Sit! Sit! Sit! Sit!
And we did not like it.
Not one little bit.

Clearly Dr Suess did not grow up in El Paso. For here, the rarity of rain make it a reason to go out and play and to "collect" it.
