"Besides, a son-in-law is half a son. We only have one daughter, Milly. When Matty marries her, it's like he's our son. Is it any of your business if I dote on my son?"

She glanced at Mr. Jenkins, who had a sour face, and chuckled, "Alright, don't sulk. If you really didn't like Matty, then why didn't you react yesterday when he called you his father-in-law?"
Mr. Jenkins snorted, "I was just sparing him some dignity. If I were really strict about it, he would never have stepped into our house until now."
