she wasn't squirming from the wrong dang saddle pad, she was squirming cuz your big ol butt was breaking her spine.
You need a Clydesdale if you want to ride a dagum horse.
Falling off a horse is no joke. I used to ride when i was younger and an old stinkin mare taught me not to play with her emotions. I would always ride her far out and then turn her toward the barn so she would think i was taking her in. She would gallop the whole way and jump the last ditch and then right before we got to the barn i would turn her around. I guess i did it one too many times and when we got to the ditch, she screeched to a halt and laid her neck down. I went flying head over heels onto the ground while she ran past me into the barn. Luckily i didn't get hurt but that was the last time i did that.
