Baby in a Basket

Preston was used to people leaving strays on his doorstep. Usually a kitten or a puppy. 
But when he awoke that morning, he found...a baby with a note written on his basket. 
"Preston, 
You probably don't remember me, but that's not important. This baby is your daughter. Her name is Lauren. I can't take care of her. I can only hope that you'll find it in your heart to give her a home and a family. 
Love, X."
