Sometimes, you know you are doing something right!
The Zoo Keeper, telling whether verbs are past, present, or future:
"A woodpecker drilled these holes...Past."
"Wolves travel in packs...Present."
"Last year we studied flowers...Past."
"Jesus loves me....Past, Present, and Future!"
Other times, even when it sounds wrong, you know it's right:
The Horse Whisperer: "I wish I didn't have to do Algebra today. *sigh*"
Me: Okay, don't do it.
The Horse Whisperer: "REALLY?!" accompanied by a beaming face and near tears of joy
Of course, it will have to be caught up tomorrow, but sometimes a kid just needs an unexpected break.
