Becky's Riddle

Here is a little riddle to go on the blog:

Little Nancy Etticoat,
In a white petticoat,
And a red nose,
The longer she stands,
The shorter she grows.

If you can answer this riddle write the answer on a piece of paper
And hand it to Becky at school. There is a prize for the first 3 people to get it right.
Happy thinking!

Thanks, Becky
