Doesn’t take much

Driving to school we pass many horses.  The boys are chattering in the backseat and then I hear a burst of laughter.  Jayce is laughing and doubling over.   Through gasps of air he says,

“That horse totally farted!  I saw it’s tail go flying outward from it!” 

David, without laughter, says calmly, “Jayce, Horses just swish their tails.  It wasn’t a toot.”
