I was doing a PPE years ago, and this little buckskin pinto mare was standing in crossties while I pulled a front shoe.
When I pulled one of the nails, it pressed on the quick, and she sat back a bit, resulting in a board being pulled out of the wall, causing a schoolroom sized blackboard to fall, which in turn caused a ladder leaning against it to tip aislewards and end up on the mare’s back.
She stood there shaking a bit, but stood, while I, having seen my life flash before my eyes, removed the ladder.
A colleague who was there turned to the parent who was having the PPE done (first horse for his kids) and said, “I don’t care if this mare is crippled. Buy her.”
He did, she worked out fine, and I kept an eye on her because I considered buying her for my niblings, but never got the chance–she had a waiting list.
