Cirque du Soleil Lunging

Can someone please explain to Harry that behaving like one of the Cirque de Soleil acrobats on the end of a line is NOT lunging. That antics and displays are not impressing me, that bouncing off the ground like it’s a trampoline is not funny. That other horses can and do lunge beautifully and it can be helpful to their riders. That lunging is like a dance between a rider and a horse where the horse pays attention to the slightest cue. That what he’s doing at the end of the line is not lunging. *Sigh*

The Pièce de résistance to this particular grey horse is to buck and fart and generally carry on for 10 minutes, followed by producing about 30 seconds of nice work and then just on a horsey whim he turns in,  halts and gives me the horsey equivalent of a look that says TaaDaaa! “Are we finished now?”
