Molly

"My name's Molly. It is an old-fashioned name, and I was christened Mary. But Papa likes Molly."

"That's right. Keep to the good old fashions, dear."

"Well, I must say I think Mary is prettier than Molly, and quite as old a name, too," said Mrs Hamley.

"I think it was," said Molly, lowering her voice, and dropping her eyes, "because mamma was Mary, and I was called Molly when she lived."
