Getting a Little Exercise

I was washing dishes when a certain three foot tall individual ran past me.  Five seconds later, he did it again.  And again.

"Bubba," I said.  "What are you doing?"

"Running!" he said whipping by.

"I can see that.  But why are you running in circles around the house?  That's a good way to get hurt."

"I need exercise."

Exercise?  "Dude, if you wait until it stops raining, you can exercise all you want outside."

"But Mama, I have to fill in the chart."

"What chart?"

"The exercise chart from school.  We have to exercise for thirty minutes every day.  And if I try to wait for it to stop raining, it might not ever stop.  So I'm doing indoor exercise."

And off he went to run in circles for another twenty minutes while I sat and watched.
