We raised thoroughbred Thoroughbreds!
My sis in law's husband was very intelligent, but was really persnickety about.... well, about everything. I remember he corrected me about my misuse of the word cement when I should have said concrete. Oooo, how criminal! It was one of his pet peeves. One of millions that is! I felt sooooo good when, one day, he was grumbling about the misuse of the word thoroughbred. He didn't know it was also a breed. Heheee. I just let it go, but was no longer intimidated by him.
Isnt your sister-in-laws husband your brother ? (head scratching )
