My Pet

Once, a while ago, just far enough for you not to remember, there was a family. Now, this family was perfectly normal. A mother, father, two little girls, and a cat, all bundled up in a cottage just outside London.
The mother and father were two perfectly normal responsible loving parents. The elder of the sisters was Lily, an intelligent ten-year-old with auburn hair and a love for books. The younger daughter was Petunia, dubbed 'Pet' by Lily was a curious nine year old and a fascination with fantasy. Jo, was the cat, a simple white tabby with long pearly whiskers. The whole family lived in happy harmony together.
One perfectly usual lazy Saturday morning, Mother and Father woke to look out the window and see their girls hard at work in the garden, Every Saturday morning, the girls would jump out of bed at dawn, to rush through their chores. If they finished their Saturday chores so their parents could drive them to town for the day.
"Hurry up with the carrots Pet!" shouted Lily, who was clipping parsley.
"I am! These carrots are big!" squeaked Petunia, who was covered in dirt.
"I call dibs on the shower!" called out Lily, running towards the house.
"Waiiiiiiiiit!" shrieked Petunia, she ran after her sister, not noticing the envelope on the porch.
