A sudden change of mind
My Dearest Susan,

Sweetie of my heart. I've been so desolate ever since I broke off our engagement. Simply devastated. Won't you please consider coming back to me? You hold a place in my heart no other woman can fill. I can never marry another woman quite like you. I need you so much. Won't you forgive me and let us make a new beginning? I love you so.

Yours always and truly,
John

P.S. Congratulations on you winning the state lottery.

An Unusual Vet
There was once an aspiring veterinarian who put himself through veterinary school working nights as a taxidermist.
Upon graduation, he decided he could combine his two vocations to better serve the needs of his patients and their owners, while doubling his practice and, therefore, his income.

He opened his own offices with a shingle on the door saying, "Dr. Jones, Veterinary Medicine and Taxidermy -- Either way, you get your dog back!"
