Our homeschooling lesson of the day, discussing which birds migrate south for winter, was perfect timing: the snow was coming down thick and we were cold.
"Geese. Ducks. Cardinals?" said Sara, with some uncertainty. Then, before Jesse could jump in with correction on what she knew was probably a wrong bird in that list somewhere, she continued proudly. "And they all fly in a 'V' shape as they go south, which stands for 'vacation.'"
